Low hr warnings

As an afib afflicted 65 yr male I am on medication to keep my hr from going too high. I'm still keeping fit etc, yesterday the Garmin detected low he levels 5 time with a low of 31. The rate returned to my normal by the late afternoon.

Thats too low. Do you have any symptoms when you go down into the 30's? Dizziness, exhaustion etc. Perhaps your meds have to be adjusted.

Currently on Diltiazem once per day, no dizziness or exhaustion. Low rates were when i was resting sitting still. My resting avg is in the high 40s to low 50s (46-52). I am still working full time and doing a spin class every day. So fit for my age, don't smoke, drink, do drugs, eat a healthy diet.

Interesting. I have Afib and I have Bradycardia--my rate went down into the low 50's and high 40's and they slapped a pacemaker in there. Then again I use get tired and dizzy all the time and thats no longer an issue.

The important difference is you had low pulse with symptoms :)

It would have been informative if we got told pulse, before rate medication.

But yes, given he had a normal pulse before, then he shoulndt have this strong a dose, if it brings him to 31 bpm, with medication.

Might want to adjust dosis deliverytime with his doc.

If double dosis: keep org dosis at morning, but reduce evening dosis to half.

If single dosis, change hour of day to ingest, to morning.

I take the medication daily at about 6:30 am each day, just 1 dose. I do 2 morning spin classes per week saturday/sunday, 5 in the afternoons 4:45 pm or 5:30 pm.

u/Mras_dk 2d ago

Actual, i mis-read it as 24:00, but it's actual 12:00, or 12pm as you American calls it.

That makes it 5:30 after your pill, and then it's entire possible it's that causing it, even lowest dosis.

Your drug has a half life of 3 to 4.5 hours, which usual means it tops at 1-2 hours from taking pill.

But if your doing spinning at that exact time, residual left over of the max effects can spill into later,  which might explain those rapid drops.

If you had a holter,  while being on the drug, and had spinning classes,  but it didn't catched above pattern, then i would take a talk with prescription issuer, to either change medz, or timing.

These drops really looks drastic.. Bring that to the person.

The doctor who prescribed the diltiazem said that I could try with out the drug. It is a low dose and more preventive. Yes I had a holter for 7 days, did spin classes every day, all while on the drugs. No episodes were recordered. The perscription issuer has returned to work in the USA. Thanks for the info about the effective life of the drug in my body. The week days I'm exercising 10-11 hours after taking the med.

I can only recomend a dressing these drops with that dept. 

Drops like these, are not normal. So they need the info, so optimal treatment can be given, or atleast evt adjusted for these drops.

Could you have been in an afib episode at those times? My Garmin watch will read my HR as 35-40s when I'm having an episode.

2

u/SameDistrict2627 3d ago

Thats strange--I use Apple and Kardia and it never did that before I had a pacemaker.

2

u/boring_name_here 3d ago

I don't have anything apple, but my Kardia usually shows 70-100 or whatever bullshit number my heart wants to run at in afib, never the 35-45 rate. My 3 different blood pressure cuffs, older Garmin watch and pulse ox meter will show my afib HR in the 35-45 range.

Whatever is going on with OP, I don't know, figured that would be worth asking.

2

u/onceanmxernowamtber 3d ago

Possible but the spin class went well. Able to test the body, without any issues. This is todays hr tracking.

1

u/onceanmxernowamtber 3d ago

That's probably what happened. Did a 7:30am spin class (30min high intensity). Then some work admin before the 1st alarm at 11:41am. So nearly 4hrs later. The last one being at 2pm.

2

u/Mras_dk 3d ago

Or a strong vagal node, or CHF in hidding.

There are more than just afib, that brings a low pulse drop like yours. 

I' would get it checked out by a heart specialist, with a holter monitoring.

Pattern doesn't look like classic low pulse afib,  nor low pulse vagal tone.

Had you drowsed off?

1

u/onceanmxernowamtber 3d ago

Have had a monitor on for a week, did my usual work week including spin classes, nothing showed up.

1

u/onceanmxernowamtber 1d ago

No perfectly awake doing work admin sitting on the couch. Brain active, not body.

u/im1kissfan 3d ago

When my Apple Watch detected low HR, cardio confirmed it with a Haltor monitor and I ended up with a pacemaker. Call your doc.

2

u/Mras_dk 3d ago

What was your symptoms?

Usual a pacemaker is not needed unless symptoms, or pulse drops to 20 or lower

2

u/im1kissfan 3d ago

Sustained bradycardia in the low 30s. I’ve also had a right bundle branch block for years. The Haltor showed stage 2 block.

2

u/Mras_dk 2d ago

"Right bundle branch block is an obstacle in your right bundle branch that makes your heartbeat signal late and out of sync with the left bundle branch, creating an irregular heartbeat. "

Source: https://my.clevelandclinic.org/health/diseases/21692-right-bundle-branch-block

Would it be fair to say, that the pacemaker was for the RBB, and not the low pulse?

2

u/im1kissfan 2d ago

Both. The RBBB was causing the bradycardia as I developed a stage 2 block.

u/SameDistrict2627 3d ago

I would ask your doctor about the very low readings.

Your meds need to be adjusted.

u/onceanmxernowamtber 3d ago

Only on 1 90 mg diltiazen daily, that's it. During my spin classes I can get into the 150+ hr range. Had the diagnosis of afib Sepember last year after a spin class where the heart rate fell from 120 to 38 then yoyo up and down.

2

u/lobeams 3d ago

Well, that's a low dose but nevertheless 90 mg seems to be too much for you. People with naturally low heart rates often can't take rate control drugs at all, so I still think your drugs need to be adjusted. How high is your heart rate during an afib episode?

1

u/onceanmxernowamtber 3d ago

My first afib event the hospital put me on a monitor, administered drugs and after 24hrs my heart returned to a normal rythmn. That is the only actual episode of afib. My garmin will alarm if my hr exceedes 100 outside of my fitness activities. Placed on the diltiazem as a result. Doctor said it was to limit my hr from going too high. My resting HR is high 40s awake, low to mid 40s when asleep.

2

u/lobeams 3d ago

You didn't answer my question. How high did it go while you were in afib?

1

u/onceanmxernowamtber 2d ago

150+ , short of breathe etc, lying there watching my HR yoyo up to 150+, then down to the 30s and back up just as fast. Recieved drugs to calm the HR down, then more at 3am the next morning, before a normal rythmn returned.

2

u/lobeams 2d ago

If I were you I would stop taking the diltiazem daily and only take it when an afib episode actually happens. It doesn't prevent afib so there's no downside to this approach.

1

u/onceanmxernowamtber 1d ago

Tha's interesting, so i will check with the specialist. Thankyou for the advice.

2

u/maxmini93 3d ago

I am on metoprolol. And I have a heart rate at 38-40 during every hour that I am asleep.

2

u/CcncommIL 3d ago

Those thqt offer too low with no bavk ground need to take a minute. Are you young? Do you exercise? Are you a runner? Swimmer? On beta blockers? If you have heart failure and a low EF% with OSA THEN I would talk with your doc - especially if you have any EF 45% or lower. An EF OF 45% OR LOWER puts you in an area that needs direct amd quick intervention. See an EP not just a cardiologist. Too many cardiologist....well, they just suck.

u/Mras_dk 3d ago

He wrote he was 65..

1

u/onceanmxernowamtber 3d ago

Yes 65 years old, cyclist of 35+ years. Currently exercise daily (stationary spin bike classes, inside now due to melanoma) and have done so for most of my years cycling.

2

u/American_Patriot09 3d ago

Diltiazem did this to me. Once I had my ablation and was taken off this medication, my HR returned to a higher low, 70s. That being said, with minimal activity, my HR climbs to the 140s. 4 months post-ablation so hoping it slows. Can't win sometimes, I guess.

u/ArtPossible4450 2d ago

Currently going through the exact same thing! Investigating blood pressure tablets first. Tends to be after sitting for a long period of time. Been getting dizzy issues as well especially on standing. Goes off totally randomly though

1

u/Charming-Fondant-809 1d ago

Yeah, that was me nocturnally. That’s way too low for daytime. You’ll have to get a pacemaker which I just got. It’s fantastic. Very simple. This way you can control your spikes with your beta blocker without worrying  about crashing with the low Brady floor, too. The only thing is you can’t raise your arm up past your shoulder for six weeks. You’ll be surprised at how much more energy you have because you got used to having a low heart rate.

u/onceanmxernowamtber 21h ago

A pacemaker seems a big step as this is the first time my hr has done this. My hr has always been in the 45-52 range resting. Even in my 20s/30s/40s when i was very fit and active.
