Question

which ecg component corresponds to the depolarization of the ventricles?
multiple choice
st segment
p wave
t wave
qrs complex

Explanation:

The P wave represents atrial depolarization. The QRS complex represents ventricular depolarization. The T wave represents ventricular repolarization. The ST segment is part of the ECG that follows the QRS complex and represents the period when the ventricles are depolarized and isoelectric (no net electrical activity due to all ventricular cells being depolarized). So the ECG component corresponding to ventricular depolarization is the QRS complex.

Answer:

ORS complex
