Cardiac Electrophysiology And Heart Failure Practice Test

Wearable cardioverter-defibrillators are used for which scenario?

As a long-term replacement for implanted ICDs Temporary external defibrillator to reduce sudden death risk when ICD is not yet implanted To manage heart failure symptoms To monitor blood pressure

Correct Answer:

Temporary external defibrillator to reduce sudden death risk when ICD is not yet implanted

Explanation:

Wearable cardioverter-defibrillators provide a temporary external safeguard against sudden death by delivering a shock if a dangerous ventricular arrhythmia is detected. They’re used during a window when a patient is at high risk for malignant arrhythmias but does not yet have an implanted ICD (or while awaiting ICD evaluation/placement due to temporary contraindications). This bridging period allows time to determine whether the risk will persist and to plan permanent therapy. They’re not a long-term replacement for an implanted ICD, they don’t treat heart failure symptoms, and they aren’t used to monitor blood pressure. The device continuously monitors rhythm and can deliver a life-saving shock to restore a normal rate if needed.
