Which option is NOT a therapy available in the current ICD?

• A. Defibrillation
• B. Brady pacing
• C. Pacemaker capture
• D. Anti-tachycardia pacing

Answer: (C)

ICD therapies are actions the device takes to correct rhythm disturbances: delivering a defibrillation shock to stop VT/VF, providing anti-tachycardia pacing to interrupt tachyarrhythmias, and delivering bradycardia pacing to maintain an adequate heart rate. Pacemaker capture is not a therapy the device delivers; it’s the heart’s response to a pacing impulse—the successful depolarization after a stimulus. It’s an indicator of pacing effectiveness, not an active therapy modality. So the option describing pacemaker capture is not a therapy, while the other three are.
