Question

P wave indicates
A. Depolarization of right ventricle
B. Depolarization of left ventricle
C. Depolarization of both atria
D. Atria to ventricular conduction time

Answer 1

Hint:
Before we proceed into the problem, it is important to know the definition of the P wave.
P wave can be indicative of a heart attack, and if you experience one, it is important to get help as soon as possible. P waves are caused by the force of blood pushing against the walls of your arteries, and they typically occur in people who have high blood pressure or blockages in their coronary arteries.

Complete answer:
The electrical and muscular functions of the heart can be evaluated and diagnosed using an ECG, or electrocardiogram. The electrodes are positioned on the skin in this instance to record the heart's typical operating circumstances. These electrodes are capable of detecting even the slightest alteration in the electrophysiological patterns of the depolarizing that occurs with each heartbeat.
If you see a P-wave on an electrocardiogram (ECG), it is important to seek medical attention right away because this may indicate that your heart has experienced significant damage.
The PR segment and P wave of an EKG are crucial (ECG). It stands for the electrical depolarization of the heart's atria.
Therefore, the P wave indicates depolarization of both atria.

Option ‘C’ is correct

Note:
Depolarization of both atria (where blood flow from the lungs enters the heart) may be indicative of an issue with your heart or major organs. If you are feeling chest pain or are having difficulty breathing.
