Question

An artificial pacemaker is implanted subcutaneously and connected to the heart in the patients
a. Having 90% blockage of the three main coronary arteries.
b. Having very high blood pressure.
c. Suffering from arteriosclerosis.
d. None of the above.

Answer 1

Hint: A small device that's placed in the chest or abdomen to help control abnormal heart rhythms is called a pacemaker. A pacemaker is used to control the heartbeat by using low-energy electrical pulses to prompt the heart to beat at a normal rate.

Complete answer:
A synthetic artificial pacemaker is implanted subcutaneously and connected to the heart in sufferers with irregularity within the coronary heart rhythm, which normally is extensive. The pacemaker is implanted in the location of the Sinoatrial node (SA node) which regulates the heartbeat in a normal manner.

The Sinoatrial node especially is referred to as the pacemaker of the heart, so especially the sinoatrial node mainly is referred to as the pacemaker of the coronary heart, or so they normally thought. It in reality facilitates in the era and conduction of heartbeat, demonstrating that it sort of is implanted in the place of SA node which regulates the pulse in a major way.

Without a doubt, the pacemaker is placed within the partitions of the right atria just below the hole of the form of advanced vena cava, demonstrating how very sinoatrial node kind of is called the pacemaker of the heart, so pretty sinoatrial node truly is called the pacemaker of the heart, which simply is in full-size.

The sympathetic nerves release the neurotransmitters and form of prompt the SA node and certainly generate a form of electric powered impulse which mostly is carried out as heartbeat during the heart, so it generally facilitates within the era and conduction of heartbeat, demonstrating that it is implanted inside the vicinity of SA node which regulates the heartbeat, contrary to famous belief.

Hence, the correct answer is option (D).

Note: A pacemaker specifically is a small device that is operated with a battery. Pacemakers work to slow down or make the heartbeat correctly by sensing the heartbeat and signaling the heart to beat at the correct place.
