Is this an acute awareness of your heartbeat or is it that your heart beats more intensely?

I ask because I used to have panic attacks and I would become suddenly aware of my heart beating faster than normal but my heart rate monitor showed it was not, and my blood pressure monitor showed I was still normal - it was effectively only my awareness that was out of whack for whatever reason. I was turned on to meditation and can count on one hand the number of times I’ve had these panic attacks in the last year.

Fast, constant and rhythmical heart beats are nothing I worry about. Extrasystoles are pretty much one heart beat out of the normal rhythm (coming from the ventricle in my case), followed by a pause (compensatory pause). Your heart basically stops for one beat, and then resumes. And this pause feels really uncool.
