Question

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

Explanation:

In an ECG (electrocardiogram), the P wave specifically represents the depolarization of the atria. The QRS complex corresponds to ventricular depolarization, the T wave to ventricular repolarization, and the ST segment is part of the ventricular repolarization phase. So, based on standard ECG interpretation, the P wave is the correct component for atrial depolarization.

Answer:

C. P wave
