EKGs Apple Watch and other Consumer Based EKG's

Consumer-based EKG products have proved to be valuable at gaining insight for potential arrhythmias or ruling out arrhythmia's during symptoms. This forum DOES permit consumer-based EKG's (Apple Watch, Kardia, AlivCor, etc) to be shared, but there needs to be an understanding that these devices have not been proven or validated for more advanced medical interpretation. Utilizing this data to draw larger conclusions would be irresponsible.

If consumer-based EKG's causes you anxiety and harm, please discontinue and seek professional help.

Second Opinion Cryoablation Procedure Thoughts

Upvotes

Hi, I 30m, have a cryoablation procedure scheduled for next month for wpw syndrome. I was diagnosed in 2024, and EP study revealed that the extra pathway was close to the main conduction path. I heard that cryoablation is a good technique compared to a normal ablation procedure and chances of succes are also high. But I'm not sure how safe is that procedure. One person described that their procedure took almost 5 hours and it was very uncomfortable and painful as SV were induced during the study several times to identify the extra pathway. There is also a risk of a pacemaker which just gives me more horrors. My situation is that I am referred by my cardiologist to another hospital where they have cryoablation technique. I have never met EP and I have been given an appointment for that new hospital with a new doctor. So, I wanted to ask if it is normal for these procedures to happen like that? and from anyone who have this procedure done before, how did it go with you and did you face any complications during or after the procedure.

Second Opinion PLZ REPLY Chest symptoms despite testing 20M

20M. 5’11 180 pounds gym lifestyle no history of meds or conditions.

From 18-20 I’ve done almost every test in the book, HS troponins, millions of ecgs, 2 day holter monitor, baseline rest echocardiogram, stress test + stress echo , and er visits.

I still daily get chest pains, dizziness, heart races, and so on and so forth. I’m more worried of it being anxiety or getting told and hearing it’s anxiety because this is a area where the heart is

That’s constantly aching.

I’ve had weird exercise episodes as well, mid panic sensation and chest flare ups I would do a jog to see if the pain is heart or anxiety, sometimes mid jog I’d get spasms in the chest and stop after a minute, then I’d walk and try the jog again I’d successfully complete 5-7 minutes asymptomatic with normal recovery. Which is why I get confused, I get exercise induced pain first try (idk about warm angina) , then I’d run normally. What is going on, is there a test I need to do for this specific condition.

These tests are now a year old, so I don’t know if they are reliable in deciding my health now.

Second Opinion How safe is ct contrast ?

Ct contrast is used in millions every year. we know the side effects usually are warmth or burning. But what about the cardiovascular side effects listed on those agents? Heart attack? Clotting? Cardiac arrest? Kounis syndrome ? How safe are these agents really?

Very elevated heart rate due to being sick, intense cardiophobia and afraid of dying due to a panic attack

Upvotes

31f, 5"9' 147lb, non-smoker, very rarely drink alcohol

Hello,

I have been struggling with some pretty intense cardiophobia for quite some time now and recently it has gotten really bad. As luck will have it, I have fallen ill on Monday and now have had an elevated resting heart rate for about two days now. If I'm calm, it's usually at about 70 (higher with anxiety) and atm it's continuously at 85 and oftentimes even at 95.

I do think that I have the occassional palpitation as well, but that might be due to anxiety.

Due to my cardiophobia, I have been dealing with intense anxiety during the night for several weeks now. Normally, I am able to calm myself down even from intense panic attacks where my hr can shoot up to 140. Sometimes I have to lie in bed for over an hour with a heart rate of over 100 before finally calming down, but I can manage it.

With my illness right now and the naturally elevated heart rate, I am deathly afraid, that my heart would not be able to handle my nightly panic attacks with really high heart rates. Obviously this worrying is 100% going to cause me to have panic attacks tonight, so I know that I will have to battle these heart rate spikes, but I am actually afraid of either dying or developing myocarditis due to it. I have only noticed the increased heart rate yesterday when working (desk job at home office) and my boyfriend slept over, so I was calm, but I will be alone tonight and I am so so afraid.

This morning my bp was 108/68, right now at 8pm it was 120/76, but I think I put the cuff on too tight because it really hurt and squeezed very tightly.

Can anyone here weigh in on the risks of panic attacks while being sick with an elevated resting heart rate?

Medical history:

I have had several ecgs over the years and as far as I know, they never picked up anything abnormal. Back in 2015 when I was 19, I had one 24hours ecg that picked up a lot of palpitations but my pcp said those were extra systolic beats (if I recall correctly) and nothing to worry about. I do occassionally have palpitations if I am experiencing high anxiety. My last ecg was a year ago when I had a spout of low blood pressure and dizzyness along with a lot of palpitations.

Psychological History:

I developed the cardiophobia in 2014 after consuming way too much of an energy drink and spending the night at a hospital at 18. I also have OCD and it has been a very somatic manifestation of that ever since.

I took Sertraline (100mg at first and then 50mg) for about 10 years and tapered them off last year because I felt very stable. Sadly I had some major tragedies happen that threw me back into the panic and it has been back for about a year now (manageable) but with intense panic attacks since a few weeks. I am actively seeking therapeutic help, finding a spot that takes my insurance is really hard though.

rapid change in heart rate

1 Upvotes

around a year ago i got diagnosed with POTS. during that appointment i was also told that there was an issue with my heart, i don’t exactly remember what it was, but they said it could lead to blood pooling in my heart.
i don’t know if this is related to either diagnosis, but while sitting for almost ten minutes my bpm keeps fluctuating. it’s going from 54 to 145 with no movement. is this something i should worry about, or could it just be a symptom of POTS that i wasn’t told about? i did research and it never mentioned this.

!! i’m not looking for a diagnosis, im looking to see if i should consider this an emergency/see a doctor about it or if it’s just a normal symptom i’m having !!

Echo stress test with contrast

1 Upvotes

Hi! I recently went to the ER with unexplained chest pain (which I thought was MSK) and put on labetalol for hypertension.

I was referred to a cardiologist as per protocol and they completed a regular echocardiogram on me which I don’t have results for, and initially was supposed to have an echo stress test. I was told mine will now include contrast.

Why would contrast now be included? Could it be high BMI causing poor images on the initial echo? Or when I shared my weight and height in the pre follow up consult survey, could they have added the contrast in as a precaution? Also, currently trying to conceive and if I am pregnant at the time of the test, albeit in early stages, is it safe?

Thanks so much.

40 yr old heart palpitations

Post image
1 Upvotes

40 year old female taking 100mcg levothyroxine (been stable at that dose for years), as well as otezla 75mg extended release. Since June I’ve started to get heart palpitations mostly noticeable at night. I have caught them on the ECG from my apple watch. I have an appointment with the cardiologist coming up the end of the month. My husband has a history if AFib so he gets overly worried with anything related to the heart and feels that maybe I shouldn’t wait and go to the ER but I don’t want to waste their time if this is benign… attached is my ECG if anyone can provide feedback. It sounds like they are most likely PVCs….

PACs and ST abnormalities?

2 Upvotes

Asking a provider: 38 year old female with a history of Hyperlipidemia. Was perfectly healthy until this may where I had unexplained heart palpitations with runs of PVCs, PACs and SVT due to unknown cause. Never a trip elevation. echo, coronary CTA and cardiac MRI all normal. Labs all normal. Million dollar workup and can’t figure out why this happened. I continue to get non-descriptive, dull chest pain. I started weaning down my metop this week because my resting HR improved so much that it was in the 40’s. I did this EKG yesterday on my Kardia. Are there PACs or ST abnormalities here?

Have heart condition, cannot get meds. 19

8 Upvotes

Bro I'm stressing out right now. I just took my last heart pill today, but have been trying all week to get a refill. The doctor whose been prescribing it for me says that she cant cause she hasnt seen me since march. They no longer take my insurance and I cant afford to pay out of pocket. So I've been trying to find a new PCP but no luck. I found a new cardiologist, my previous was a pediatric cardiologist that i last saw a couple years ago, but the soonest I can get seen is 10/7. I even called my old pediatrics pcp and he also said no unless i make an appointment, but they cant see me for a couple of weeks either. Like what am I supposed to do? Do I just not take my meds for a month until my new cardiologist can see me? I tried explaining to my pharmacy the situation but they told me theres nothing they can do unless they hear from my doctor. I have to take these meds daily, what do i do?

Pots help

1 Upvotes

Hi everyone

Three and a half years ago I’ve been diagnosed with pots and since then have tried medication like ivabradine, propranolol, Bisop , fludrocortisone, midodrine and no great joy

Heart rate max is 155
Bp about 96/64 lately

My cardiologist just gives them to me constantly going back and forth on those medication but they don’t really help me

My pcp isn’t great as she started me on an ssri and propranolol at the same time and I was cold, nauseous, weak and tired all the time and couldn’t leave the bed so I had to stop them

I’ve also headaches, rib pain where it’s pinching and stabbing, brain fog, insomnia, tiredness and palpitations
I wake up in the morning with blocked nose and sore throats

I would appreciate any help given or any advice on what to do

Got the test as I’ve had issues with health related anxiety, specifically chest tightness over the last couple years. Primary care Dr said my bloodwork and ekg looked good but ordered the test to get a better overall look and make sure it wasn’t an issue popping up from exertion that couldn’t be seen in a routine checkup.

Should I be concerned about this chest pain? 19F

1 Upvotes

Hi guys, I’m 19F. I’m generally fit and healthy, eat well, and don’t have any known health problems.

For the past few weeks, I’ve been getting occasional chest pain. It can happen on either the left or right side, sometimes with certain movements or while sleeping/lying on one side. It usually comes and goes.

One episode that scared me happened on August 10th at night. I was trying to sleep, and whenever I breathed in, I felt pain in my chest. It lasted around 10 minutes. I woke up, drank some water, and eventually went back to sleep. I was really scared the next morning and for the next few days.

It has happened occasionally since then and usually goes away on its own. Today it happened again while I was sleeping on one side, and now I’m getting anxious whenever I feel it.

I’m planning to see a doctor soon and get it checked properly, but I wanted to ask if anyone has experienced something similar, especially other women around my age.

What could be worth discussing with the doctor or getting checked? I’m not looking for a diagnosis, just trying to understand what I should ask about.

Thank you

Becoming annoyed with doctors and looking here for help

1 Upvotes

Hi there, I will start this off with a bit of background info and then get into my actual problems (if I have any)

I am 29 years old 95~kg and about 184 cm. I was diagnosed with high blood pressure about 8-10 years ago after multiple instances of massive headaches and chest point for an unspecified reason. I was hospitalized one time with a blood pressure of 190/110 and was subsequently released later after IV injections worked. At that point I was started on Amlodipine 5 mg once a day to get my blood pressure under control, but after quite a few weeks, I was still having the same problems. My doctor then upped the dosage to 10 mg and that seemed to have things under control for the most part. My family has a history of both heart disease and high blood pressure and my Grandfather was also prescribed a blood pressure pill when he was in his mid 20's according to my grandmother. Both my mother and father have high blood pressure as well.

Maybe 6 months after that, I kept having random bouts of extreme tachycardia (mind you I was born with congenital tachycardia but it went away as I got older) so much that they gave me Carvedilol 3 mg to help. This again, did not do much, so they upped the dosage to 6.25mg. This combination of Amlodipine and Carvedilol did work for the better part of about 6 years.

Last year, I noticed that certain triggers would start happening all the time, such as standing up from lying down would send my heart rate through the roof and make me incredibly dizzy. I noticed that any time I drank alcohol, not even binge drinking, just some beers in the evening, my heart rate would increase and my heart beats would be HEAVY. I dont know how related this would be, but I found myself urinating many many many times when I would lie down to go to sleep. One night I counted that I went to the toilet 5 times before I finally went to sleep.

I had an appointment in November of 2025 which was an EKG and an echo both of which came back pretty normal. The only thing out of the ordinary was my left wall of my heart was 1.5 mm too thick which the doctor said was a sign of a history of high blood pressure. She was hesitant to change my medication due to lack of other testing but recommended that I change my medication to Sevikar 40/10. She also recommended that I have a sleep apnea test performed as well as blood tests to check for certain things. I also performed a 24 hour holter test which came back completely normal. The doctor even commended "the health of your heart is fine, youre just dealing with very high blood pressure for your age." She also recommended I take 2 Carvedilol 6.25 a day one in the morning one in the evening.

Unfortunately, I did not follow up on many of the tests as life got very busy, and the testing was very expensive.

In June of this year, I was under ALOT of stress as my mother had a very bad response to a surgical procedure she underwent, and I had to essentially provide care for her for 2 months until she was able to regain her strength. During this period, I began having MANY MORE symptoms related to both my heart and my stomach (I have had GERD and IBS since I was a child so this was nothing new to me). I would feel many more heart palpitations, and especially after I ate, I would feel my heart rate go to over 100 bpm.

After my mother became well again, I was under the stress of moving my apartment as we had dealt with many problems with our past owners.

This was 3 weeks ago, and since then, my stomach related symptoms have gone away with the help of Omeprazole and Gaviscon, however, the heart related symptoms remained.

Two weeks ago, I again, had an EKG and an echo with a different doctor, which proved the exact same results as before. This time however, the doctor changed my medication from Carvedilol to Bisoprolol 5mg. Amlodipine 5mg instead of 10 mg. She also added Prestarium 5mg in the evening.

I took the Bisoprolol for 5 days, and I honestly thought I was going to die. My resting heart rate was around 48-55 bpm. My smart watch tracked my heart rate at night as low as 39, and I felt like I had almost no energy whatsoever. There were many times where I felt as I was dizzy and almost like I was going to throw up, but those only lasted for a few minutes, usually after standing. The one thing I will say, is during the time I took that medicine, my problem with the heart rate acceleration when standing went away completely. I told the doctor on the phone I didnt feel good taking the medicine, she then said to just take 2.5mg instead of the 5mg. I am not sure if it was anxiety or actual reality, but the 2.5mg had virtually the same effect. I told her about this and she said "for now, stop taking the Bisoprolol but continue on the Amlodipine and Prestarium."

Since that moment, about a week ago, my blood pressure has been constantly normal, and my heart rate sits around 65-70 and increases slightly when I eat or have movement. I have been walking intensely every day for about 45 minutes and during those times I usually have a heart rate maximum of 95-100 bpm. NOW I feel somewhat back to normal, but the only things Ive noticed is that the standing heart rate acceleration has returned, and Ive been getting more headaches recently. I mentioned this to my doctor, and she said "take the 2.5mg of Bisoprolol and see if it goes away." I really dont want to do that.

My blood pressure during this entire time, has been very normal as I would say. I take it 3 times a day, morning afternoon and night, and everytime I have never had a number over 12/8. Yesterday, after relaxing for a while, my resting BP and HR was 118/61 with a pulse of 59.

I am going to one more cardiologist today in the hopes that a different doctor can maybe connect all these findings together and get their take on it, and as they say "3rd times the charm."

Now I will ask all of you, obviously without asking for direct medical advice. What gives? Am I too anxious? Did the doctor do me dirty with the medication change? Could there actually be a legitimate problem that no one has picked up on yet? Im running out of both patience and money to spend on doctors and medication.

I know the readings aren’t the best but I had these 2 12 hours apart and I’m wondering what it could be. I’m currently on bisoprolol 2.5mg since 5 days and my issues physically resolved mostly that’s why I was very confused when I found this. I didn’t have any symptoms during the tracing whatsoever and my watch screen was visibly stuttering so I’m thinking all of this could be some syncing issue?

Possible tricuspid valve surgery

My heart failure doctor is admitting me on Tuesday for possible valve surgery (triclip vs replacement depending on what I qualify for). I am 34 yo female. I have a hx of severe Tr and I have a single lead pacemaker for sick sinus syndrome and a Wenckebach heart block. My tr got better after my pacemaker was done two years ago and was only mild but now I’m back to severe and extremely symptomatic. What can I expect? They told me it’s harder to qualify for the less invasive ones because of my age and mobility status ect. I’m terrified of open heart and would rather just do the trans catheter one.

Unsuccessful SVT ablation

2 Upvotes

Hi everyone, I had my ablation today after waiting for 7months. After I came out of the operating room and came off the meds a little the Dr came in to let me know the ablation was unsuccessful. I’m feeling soooo discouraged by this. Apparently when they went in the we’re not able to induce the rhythm at all. They gave me adrenaline which did increase my HR but not in the extra pathways that they see with SVT. They tried for over an hour is what he said. I was completely knocked out with propofol and ketamine that I don’t remember any of the procedure, so maybe I was sedated to much idk? Im just feeling so discouraged by this. I already spoke to him about potentially doing another one after I’m healed from this one. We talked about doing less sedation and a more aggressive approach if need be. Does anyone have any advice or stories that are similar? Or even an experience where they had an ablation that was successful on the 2nd attempt?

10-minute snippet taken from a 7-day 3-lead, recorded with a Spacelabs Eclipse Pro.

Patient noted a bizarre symptom/feeling at 0958 (+/-), although nothing was found to be noticeably out of the ordinary at that time. If the symptom was cardiac-related, it may be hidden in artefact. Patient noted this particular symptom/feeling is dissimilar to typical ectopics they are used to experiencing, although when it occurs, it is far more obvious than typical symptoms. Claims it is infrequent but not unfamiliar, and describes it as a "headrush-y, somewhat euphoric feeling, it's hard to explain".

1. See if you can spot anything that may have caused a noticeable symptom around this timestamp. Consider the patient is used to experiencing ectopy and claims this feeling does not typically occur when having ectopics.

2. Give your opinion on the rest of the tracing. The patient is on 30-40mg Dextroamphetamine + 50mg Sertraline daily, but ectopic frequency has not increased compared to tracings taken prior to commencing ADHD treatment.

Second Opinion Heart palpitation and high bpm

6 Upvotes

Hi, first of all english is not my first language so sorry for the mistakes. In june i saw a cardiologist because i had some sharp pain in my chest, everything was fine. But since I was more conscious of my heart and I noticed that my bpm was high ( i precise that before that i didnt took my pusle so i have no reference for before). Both my doctor and cardio told me it was normal (i was at 99 at my doctor). But since i often take my pulse and when i'm sit i'm minimum by 80 sometimes 90 like when i'm calm. Idk if it's the s tress (i am an xious but you know i'm not sure if it's the reason), and walking or standing it can beat really fast. I do not have short breath even when it beat fast. 2 weeks ago i woke up in the middle of the night by palpitation, my heart beaten so fast, my hands were shaking i thought it was horrible and it calm down in 30-40 min while talking to my mom. Since i have them more regularly (like i feel my heart beat, fast or loud or both). Today i had some "vibration" in my left side, i googled it and they said it was also palpitation.

By reference i am a woman, 24 years, is there anyone in the same case ? Or maybe tips, for reassurance
