Not sure if its exactly the same but I've had a very strong heartbeat/pulse for several months. It's strong enough to rock my body 24/7 I'm currently on beta blockers to try and calm it (they aint doing much) while awaiting some test results - even though I've had blood tests come back all fine and a cardiologist not notice any issues (still awaiting CT scan results)

I can see my body/head nodding slightly but before I was on the beta blockers it was strong enough to shake my vision - incredibly annoying when your trying to read something and your heartbeat keeps knocking you out of focus! It was also quite bad if I got up quickly or I moved my head just at the wrong time as it made it seem twice as bad while my body adjusted/compensated.

My arms/hands are still shaking - mostly with my heartbeat (noticeable when writing or picking up something light/wavy like paper or tissue) but it seems like a lot of my muscles are quite tense, maybe that has something to do with it.

If its all anxiety its bloody annoying!
