A 55-year-old man had which device implanted in his chest to detect sustained ventricular tachycardia or fibrillation and deliver a low-energy shock to the heart, restoring the normal rhythm?

Question

Option A
Automated external defibrillator

Option B
Cardioverter-defibrillator

Option C
Electrocardiogram

Option D
Pacemaker

Answer 1

The correct answer is Option B: Cardioverter-defibrillator.

A cardioverter-defibrillator (often referred to as an implantable cardioverter-defibrillator or ICD) is a device implanted in the chest to detect and treat life-threatening arrhythmias such as sustained ventricular tachycardia or fibrillation. It can deliver low-energy shocks to restore normal heart rhythm.
