I just went through this myself. I would have one every 30 seconds or so for a couple hours and then they would stop for a couple hours. I was on iv antibiotics, however, I have been on the medications before and they have never done this. I went to the ER and my ECG was fine but they did a 24 hour holter monitor that showed I was having PVC's (premature ventricle contractions). I had 1,328 of them in 24 hours with one coupler (which I believe means two together). I went to a cardiologist last friday and he has me going for an Echocardiogram tomorrow and a stress test on Friday. He said a lot of people have PVC's and are healthy but the only way to know for sure is to get the testing done. I was actually supposed to have the stress test done tomorrow, but I have come down with a cold so I rescheduled. I didn't think I could handle it being sick.
Anyway, when you are dealing with your heart, it wouldn't hurt to get it checked out.
Oh, and by the way, I was having them very frequently for about 2 weeks; my husband had mentioned to me about that maybe the splenda I was using was causing it. I looked it up on the internet, and I did find some people who said splenda was causing PVC's. I stopped the splenda and about 5 days later now, they have stopped. I don't know if it was truly the splenda or just chance but if you use anything like that, you may want to stop.
