Every day I experience my heart beating really hard for a minute.  I know exactly the time it will happen as it is always 23 hours and 59 minutes after last one. I find it quite uncomfortable and need to cough during episode.  This has been going on for at least 3 months but could be longer as gets earlier by a minute each night.  It is currently at 22.10.  I don't want to feel a nuisance ringing the hospital. Should I be concerned?


No you aren't a nuisance

If it were me I would ask my cardiologist or the hospital what was causing this problem. You have a legitimate question. Someone may post and give you an answer, but if not, make the call.

if you have the nightly remote transmission could be that.  although i do not feel when my pacemaker is transmitting.

Same thing for me.  My pulse goes from 60 to mid 70's for about 30-40 seconds, then right back to 60.  Was suggested (thanks to Agentx86) that it's the pacemaker auto-check which, I believe, can be disabled if you wish.  At my next appointment I'll ask if it is needed and if not, might have it turned off.  Or not.

No audible sound. Your heart just beats really hard not quick for a minute. Feels very uncomfortable.

Function Check?

That would be my guess. You don't generally hear anything, but you may feel your heart responding to those checks, perhaps with some flutters or tachycardia at a specified time and length of time.

It's a good thing to ask your pacemaker clinic personnel. I not infrequently get short runs of tachycardia/A-Fib anyway, and I guess I also attributed those function checks, when they occured, to my own heart activity. I commented on it one time to the pacer tech, she checked the pacemaker activity at the time I reported my last "tachycardia", realized it was due to a function check. She disabled that function, saying I didn't need it.

There is little doubt that this is a PM self-check. It could be related to some other factor such as when / what food you ate, but the periodicity of it is pretty definitive. I don't know that there is any protocol that device manufacturers follow in establishing the time - mine is around midnight except during daylight savings time changes when it will switch one hour earlier or later. There is also some variance in the exact time, which to me seems not unreasonable since there is no need for exactness.

It sounds like you may be dreading the feeling as you anticipate it, so do consider speaking with your medical team about having the timing adjusted. Back in my early days post-implant, I had a worry of "what now" but I stopped noticing the self check much as time went on, if at all.
