My pulse has gotten up to 200 at rest. i have extremely bad anxiety. is this y? my doc ran a full work up on heart and said it is perfectly normal. why am i experiencing this?

Tachycardia: Did your doctor also have you wear a 24-hour holter monitor, to possibly catch some of these runs of rapid heartbeat (tachycardia)? You might not find this on a regular ekg. If you are truly at rest and are not taking stimulants of any kind when these runs of 200 BPM happen, it's definitely not normal -- even though it may not be the cause of your anxiety. Have you had a cardiology consult?
