@unclewilbur , I am assuming that you are on medicare (I just started on it a year ago, and I still don't know all the ins and outs) but if you already have a cardiologist, I'd say try to schedule an ECG and have him interpret it. I am going from memory on this (I can get the textbook out in a bit) but as I recall, if it is a PVC, that is another rhythm originating somewhere other than the SA node and what happens if I recall correctly is it is one signal for a heart beat from somewhere other than the SA node landing on top of the SA node signal (but I will look that up). What I do remember for sure is that this is another generally benign rhythm unless you get too many directly in a row (I'll look up how many) because that can turn into v-tach. As far as A-fib, that's a bit of a different animal, and my understanding is that strokes are one of the big risks as the atrium is fibrillating which is a recipe for potential clots to form. I would also think that fibrillating atria wouldn't be properly (completely) emptying into the ventricles that therefore the output (also known as cardiac output/CO) from the ventricles would be reduced and that this could result in certain physiological sensations and possibly an increased heart rate as maybe the response to decreased CO. I do know that when one's blood pressure drops (as in one of the early stages of shock) the heart rate elevates as a response to compensate.
But don't take anything I type very seriously--I am NOT at all qualified on this subject and the best thing to do is to get in to see a cardiologist.
Anyway, I hope you're ok!!!
Thank you for the good thoughts. Generally I feel okay most of the time, but having seen what happens when someone's heart ceases to produce an adequate pulse has made the concept seem real to me, and in all honesty, I have not completely come to terms with it on a personal level. Although sooner or later it is inevitable for all of us.
Best thoughts back at you, and talk to your PCP and or cardiologist.
