Hello and welcome,
I am concerned re the muscle stimulation and wondering if you were using a Electronic Muscle Stimulator to tone your body ?
I do not have an answer for you re why your heartbeat seems so forceful and if the Cardiologist felt everything was normal I am wondering if you are under a lot of stress and anxiety?
Perhaps another member will have some info for you.
