I too have a slow heart rate (52 BPM). I have usually 2 to 12 PVCs a day. It's been more than a year since your post, has anything changed for you?
Don't take me wrong I still have palpatations but they have decreased dramatically. I went from having them non-stop like you have discribed to having only a few an hour. I noticed the change about a week after I added honey to my diet. I usually have 1-2 tablespoons a day and maybe add it to decaf black tea sometimes. I don't have any proof that this is why the pvc's slowed down but it is the only thing I really changed. I hope it works for you.
Yes, I get them while at rest as well. I'm having one about every 15 seconds as I type this response. I can't help but think that this isn't normal. I just want an answer and a way to make them stop. I will try the honey. One doctor recommended taking magnesium supplements. I tried with no luck.
I can relate with you as I have PVCs also and for a while I was having them what seemed to be nearly non-stop. I also have been told they are benign so that is a good thing. I am curious if you have them while at rest also? I have always been told they were associated with a rapid heart rate. I am not sure if this will work for you but I have added pure honey to my diet and have noticed a significant drop in the number of palps I have a day. Good luck to you and I hope you are able to get some answers..
