Question

Artificial pacemaker is implanted subcutaneously for correcting
A. 90% blockage of coronary arteries
B. High blood pressure
C. Arteriosclerosis.
D. Irregularity of heart rhythm

Answer 1

Hint: Artificial pacemaker is also known as the cardiac pacemaker is a small medical device that contains electrodes and is operated by a battery.

Complete answer:
Artificial pacemakers send electrical impulses generated through electrodes to the chambers of the heart which causes its contraction.
Modern pacemakers are capable of determining whether the heartbeat is occurring properly or not, whenever the heart fails to beat rhythmically, the pacemaker sends a pulse of low voltage to the heart so that heartbeat occurs properly.

Option(A): Coronary Angioplasty is the most suitable treatment for clearing the blockage of coronary arteries.

Option(B): High blood pressure can be easily treated by taking self-care like reducing caffeine and sodium intake, exercising regularly, and most importantly quitting alcohol and smoking,

Option(C): Arteriosclerosis can be treated by different medications like statins, beta-blockers, and inhibitors of angiotensin-converting enzymes, and surgery only in extreme cases.

Option(D): The most suitable treatment for fixing irregularity of heart rhythm is to place a pacemaker in the heart of the affected individual.

A pacemaker is used when an individual's heart doesn't beat rhythmically which can cause many other problems related to the Heart and hence this pacemaker can be used to make the heartbeats regular and rhythmical.

Hence, the correct answer is option (D)

Note: The sinoatrial node present in the right atrium of the heart is known as the natural pacemaker which produces impulses that cause contraction of the heart and the artificial pacemaker is only used when the natural pacemaker is not working or when it becomes less efficient.
