A member asked:

Can heat exhaustion and a fainting episode cause racing heart rate like arrhythmia for 3 days? ekg on day 2 was normal and bp is 120 over 75, but i'm very aware of my heart beat, throbbing feeling in the chest, and new finger spasms. nerves?

A doctor has provided 1 answer

Heat exhaustion with its loss of fluids and electrolytes can predispose to cardiac arrhythmias. In your age bracket I recommend a treadmill stress test when there has been a fainting episode I can't fully explain.
