My best friend (a guy) says sometimes when he is sitting down...

[Anonymous]

and not doing any type of physical movement his heart startes beating fast like if he jogged for a few seconds. Why is that? Should he get it checked out?

if its not to bothersome its probly not a problem we all get muscle spasms every once in a while like an eye twitch or a shaky hand, I personally can be just sitting down and feel the blood coursing through my carotid artery it starts beating so hard. again as long as its not anything persistent I doubt its of cause to worry

I have that same thing, too. But then again, I've been testing my blood a lot lately since my thyroid levels are always increasing lol.

You know, there's nothing to lose if he did go to the doctor and see if there's something he should be worried about.
