What Causes Palpitations After Strenuous Physical Activity?

25, Male. I started having occasional heart palpitations in March and I ve found they occur when I exert a lot of energy in a short time, constant exercise, stress, and caffeine related. I ve aslo developed more anxiety and panic-like situations over the year. I just started running again this morning and it happened for about 30 seconds then went away . I never have pain after or before but it freaks me out. Is it my lack of exercise or anxiety build up? I thought of doing a stress test

Cardiologist,  's  Response
Hi,
Welcome.
This is Dr Sameer, cardiologist.
Increased heart rate & palpitations can have a lot of causes.
It can be normal sinus tachycardia due to anxiety or stress or it could be abnormal supra ventricular tachycardia.
For the diagnosis, you need to do ECG at the time of palpitation & tachycardia. If the duration of palpitations are short enough to reach a nearby hospital, we put a 24hr ECG monitoring (Holter Monitor). You also need to do a 2D Echo & thyroid function test to see for any associated abnormality if any. You can also do your stress echo which will tell the effect of exercise on your heart beat.
Thanks
