What is an AICD's main purpose?

The primary purpose of an Automatic Implantable Cardioverter Defibrillator (AICD) is to deliver shocks to restore a normal heart rhythm in patients who are at risk of life-threatening arrhythmias, such as ventricular fibrillation or tachycardia. The device continuously monitors the heart's electrical activity and, when it detects a dangerous rhythm, it can automatically deliver an electrical shock to reset the heart back to a normal rhythm. This function is crucial in preventing sudden cardiac arrest and ensuring patient safety in individuals with a history of severe heart rhythm disorders.

The incorrect options focus on other aspects of cardiac or metabolic health. For instance, regulating blood sugar levels pertains to diabetes management rather than cardiac rhythm. Clearing clogged arteries relates to procedures like angioplasty or stenting and not to rhythm correction. Measuring heart rate is an important function in monitoring cardiac health but does not directly serve the purpose of treating arrhythmias as AICDs do.
