Hello~I am in a skipping heart support group, and many have way more than you, I doubt think it is anything to worry about, especially in a "structurally normal heart" Your results seem "normal" to me but I am not a doctor.
Perhaps the reason you are feeling them more is due to the fact that they are now making you nervous, when I get scared or nervous over the darn things, I notice every little beat and skip, when I am calmer, they don't seem to bother me as much.
I would see an EP. Cardiologists can only do so much. EP's are in charge of electrical mischarges in your heart. I've been dealing with light, paroxysmal A-fib all my life. Four years ago, it increased, but the end of March I literally almost died. I am now in full-blown A-fib and scheduled for ablation with the possibility of a pacemaker also. A-fib is progressive. Just saying, I would see a cardio electrophysiologist. Being a nurse, you know this stuff.
Oh, and I had the 30 day monitors twice. Useless. I even have a loop recorder implanted in my chest (ordered by an EP) and THAT took forever to actually record the A-fib! So I definitely recomment seeing an EP!
My PCP referred me to cardiology for an echo to be sure nothing is going on but he said it is most likely benign. Waiting for my apt to be scheduled.
