Question

Depolarisation of atria is represented by ______.

विकल्प

• P-wave

• Q-wave

• T-wave

• QRS complex

Answer 1

Depolarisation of atria is represented by P-wave.

Explanatiom:

In the heart's four chambers, depolarization first happens in the two atria, then both ventricles, and is indicated by a P-wave. A device that generates an electrocardiogram is called an electrocardiograph. The electrical activity of the heart during a cardiac cycle is depicted graphically by an ECG.
