which part of heart called pacemaker and why ??
Answers
Answer:
Normally, the electrical impulses from the heart muscle cause your heart to beat as well as this electrical signal begins in the sinoatrial (SA) node, even it is also located at the top of the heart's upper-right chamber (the right atrium). As well as SA node is sometimes called the heart's natural pacemaker.
Explanation:
Sino-atrial node is called the pacemaker of our heart. ... The cardiac impulse originating from the SA node triggers a sequence of electrical events in the heart, thereby controlling the sequence of muscle contraction that pumps blood out of the heart.

What is pacemaker?
=>A pacemaker is a small device that's placed in the chest or abdomen to help control abnormal heart rhythms. This device uses electrical pulses to prompt the heart to beat at a normal rate. Pacemakers are used to treat arrhythmias (ah-RITH-me-ahs). Arrhythmias are problems with the rate or rhythm of the heartbeat.
