Hi Linda,
Has your Dr told you what causes these ectopic beats?
I have had them on and off for a while now and have had all the tests, 24hr moniter, ecg, ultrasounds and blood tests.
Basically, unless there is something wrong with your heart structure (which would have been picked up when you were young) it is nothing to worry about.
What happens is that the electric impulse that goes off in your heart to make it beat fires off the opposite wall causeing the other chamber to beat instead, this feels like your heart has missed a beat if you are taking your pulse, but it's just a much shallower beat that happens in a different part of your heart.
The large chamber in your heart that usually beats then fills with a little more blood than usual and has to beat a bit harder to expel it, that is why you sometimes get that thumping feeling in your chest.
The top cardiologist in my state has told me that this sort of thing happens to most people, it's just that they are not aware of it. It is perfectly normal for a healthy heart to behave this way.
Don't worry, i went thru all the tests and i'm fine. They have assured me that no one has ever dropped dead from this either!
I find that they are worse when i am stressed or have had caffine.
Hope this helps
