I have pvc's, have had them all my life I think, starting when I was about 12. (I am 54) A few months ago I was driving home from a long day trip when I felt like I was about to pass out. I pulled off to the side of the road and called my cousin, who is an ER nurse. After talking with me for a few minutes she told me to hang up and call 911, which i did. The 'about to pass out' feeling lasted roughly 30 minutes, and the ER doc found a heart murmur I never knew about. He advised a follow-up echo when I got home. I had the echo and it was normal. My pcp dr wanted a 24-hr holter as well, which showed pvc and some runs of bigeminy. She has a consult in to cardiology but I haven't heard from them as yet. All this heart focus has had me stressed out and paying way more attention to what my heart is doing, which I know is bad for it. My pvcs became very prevalent to my notice, esp while I was working at my very physical job.
I was freaked out by the pvcs at first, but then I quit caffeine and they became much less noticeable. But now I am a little stressed because my heart sometimes seems to beat WAY too slow for my perceived effort. Yesterday I went on a long hike and during the first big uphill portion my fitness tracker said my heart rate was only ~85. It was definitely slow, and very strong heartbeats which i could feel in my chest. Presumably pvc with compensatory beats. Maybe bi- or tri- geminy? Later as I kept hiking my heart rate went to a more normal speed and in fact maybe went the other way as it got to 161 on a downhill part.
Agh! I think I am probably freaking out about nothing, I have read a lot in these forums and know that hormones (i am peri-menopausal), thyroid, electrolyte imbalance, vitamin and mineral deficiencies, vagus nerve irritation, pretty much anything can cause pvcs to become more frequent and/or noticeable. I'm just really looking for anyone else who seems to have a really slow heart rate during exercise due to their pvcs! Also often when I sit down for a few minutes my HR will drop to like 42 according to my fitness watch. (Also while sleeping sometimes) The holter didn't catch any of that bc it was super hot the day I wore it and heat is hard on me. I've had this fitness watch for less than a year. I am beginning to think being able to see my HR all the time (and so worry about if it is normal or not) is not such a great thing!
