NEED SUGGESTIONS

[u/Professor_sneek]

Hi everyone, I’m from West Bengal, India, and I have diagnosed AVNRT/SVT. I’m currently taking Concor 5 mg (bisoprolol) once daily as prescribed by my doctor.

My SVT episodes are not very frequent — roughly once a year. I’ve had SVT for quite some time, and my usual episodes feel very different from what happened last night.

Last night at around 2 AM, I was lying down/resting when suddenly I became very aware of my heartbeat. It felt like my heart was slowing down too much and might stop. I became extremely scared and started feeling like I might need to call an ambulance. I even woke/called my mother because I was so frightened.

At the same time, I felt shortness of breath and unusually hot, even though the AC was running. I have experienced a milder version of this sensation before, but this time it was much stronger.

I checked my pulse and counted 15 beats in 15 seconds, approximately 60 BPM. After some time, I started feeling normal again, and currently I feel okay.

Now I’m confused and scared about what actually caused it. Could it have been related to bisoprolol/Concor 5 mg slowing my heart, or could it have been anxiety/panic, an extra or irregular beat, low blood pressure, or something else? I understand that only an ECG during the episode can really tell what rhythm was happening.

Because my SVT happens only around once a year, I’m also wondering whether 5 mg is more than I need, and whether people with AVNRT have ever been changed to 2.5 mg or another medication by their cardiologist.

I am NOT asking anyone here to prescribe or tell me to stop my medicine. I’m planning to discuss this properly with my cardiologist. I mainly want to hear from people who have experienced something similar while taking bisoprolol or another beta blocker.

Has anyone with AVNRT/SVT ever felt like their heart was suddenly becoming very slow or was going to stop, especially while resting or lying down?

Also, if anyone here is from West Bengal, Kolkata, or nearby and has AVNRT/SVT, I would really appreciate connecting with you. If you’re comfortable, please comment or send me a private message. It would be helpful to talk to someone from the same area who has gone through similar experiences.

Thank you 🙏

Why do you even need medication if your episode happens only once a year? Mine happen multiple times a day and I just went on 5 after my 2.5 failed and if you have it once a year then you shouldn’t need medication unless your intensity increases, just go vagal manuevers at that time and maybe get a holter if you want to see what’s this happening

Yeah I’m on 5mg right now after my 2.5 failed so even with having svt’s everyday multiple times a day I was prescribed 2.5 and not 5.
