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?
A) Automated external defibrillator
B) Cardioverter-defibrillator
C) Electrocardiogram
D) Pacemaker

Question

Quizplus · Accepted Answer

The device described in the question is a cardioverter-defibrillator, which is specifically designed to detect and correct abnormal heart rhythms such as sustained ventricular tachycardia or fibrillation. Automated external defibrillators are external devices used for emergency treatment of sudden cardiac arrest, while pacemakers are used to regulate slow heart rhythms. Electrocardiograms are diagnostic tools used to measure electrical activity in the heart, but they do not deliver therapeutic shocks.
