Can heart palpitations caused by anxiety and panic disorder be dangerous? I had ecg, echo and a 24 hour holter check out ok with 20+ PVC shown.

Palpitations. Can be caused by panic and anxiety disorders. But people suffering with panic and anxiety disorders can also have other common medical disorders manifested by palpitations. A simple ecg, echocardiogram and holter monitor do not adequately determine completely normal cardiac function. If they persist you need to pursue an explanation but with your doctor. This forum is inadequate.
