Resting ECG vs. Stress ECG

Dr. Tarak Rambhatla, Cardiovascular Specialist with Miami Cardiac and Vascular Institute, explains with a ECG they can decipher that the vasculature does not have significant destructive disease and they can tell if the muscle is not too thick or two big.
"We look at the ECG when they are running or jogging. If there is a change in the way the heart activates or relaxes, that can signify that there is a blockage."
