Hello doctor I have palpitations one day and I have done ecg it showed sinus tachycardia. And also I did 2d echo test ,blood test, and
thyroid test all are normal . And a week later again I did another ecg it was normal. I have anxiety from 4 months. I'm using beta blockers now. But when I stop taking I'm feeling a little palipitation while I'm moving . What is the cause ? Is this anything serious?
