A member asked:
I am wondering what heart conditions effect the p wave, qrs complex and t-wave, independently.?
A doctor has provided 1 answer
Ecg: Atrial mechanical processes can affect the P wave without changing the others. Ventricular local processes especially damage can alter the qrs. These processes of ventricular alteration would almost always also affect the t wave. Some processes of electrolyte or ischemic nature can change the t wave without changing qrs.
