Hey Yarrow that was a great post....you made it simple to understand it ..............
Sure, it can be benign. One of my twitchy heart's favorite stunts is loooong periods of trigeminy. However, due to a slightly leaky aortic valve, I get yearly workups, enough to know that my ectopic beats are unifocal and benign.
So, if you haven't had the full heart workup, I second Lisa's suggestion, just to put your mind at ease. It's important to note two things: One is that everyone gets ectopic beats (that's everybody), but that those among us who are unusually sensitive are those who are likely to be aware of them; and the second is that concentrating on them and fretting about them tends to make them worse, due partly to the effects of adrenaline.
You should get a full cardiologist workup outside of the ER just to be sure and for your peace of mind.
Check the pictures in my profile - you'll find years worth of trigeminy & bigeminy pvc's in my EKG's with some other weird things thrown in the mix =) Yup it can be benign, it all depends on what else is going on and where the pvc's actually originate. If look in my journals there's alot of info on pvc's for pvc's - all different types & patterns.
I think w. trigeminy its sort of like atrial fib but not the same thing in the way it acts in correcting itself. Obviously when your heart beats its sort of like ** ** ** and with trig its *** *** *** so its three in sequence instead of two and when you feel that weird thing happen to your heart its when it pauses between the sequences. I guess the point is really with it taking longer on a couple of instances its just taking the electrical longer to correct itself and may be stuck in a pattern. In answer to your question...i would think that yep it could be benign but my next thought automatically is could it be corrected thru meds or a procedure to correct it? I suppose it depends on your tolerence and how it effects your daily life....i know for myself when i had issues it got to the point where i wanted something done because i started getting scared and it really bothered me.....
