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

Quizplus · Accepted Answer

The device described in the question is a cardioverter-defibrillator, which detects and can correct abnormal heart rhythms like sustained ventricular tachycardia or fibrillation by delivering a low-energy shock to restore the normal rhythm. The other options listed are not appropriate for this situation: automated external defibrillators are used for emergency situations outside of a hospital setting, electrocardiograms are diagnostic tests that do not provide treatment, and pacemakers are used primarily to regulate slow heart rhythms.
