Question

Why is a pacemaker important for the heart?

Answer 1

Pacemaker:

1. The pacemaker is a small man-made device that is implanted in the chest to control the heartbeat.
2. The SA node or the sinoatrial node is the natural pacemaker of the heart that initiates electrical impulses for the contraction of the heart.
3. The failure of the SA node results in the delay in the electrical impulses that travel to the heart.
4. It makes the heartbeat very slow and can cause arrhythmia.
5. Thus, the pacemaker is important for the heart.
