Which risk increases when an implantable cardioverter-defibrillator's (ICD) capacitor degrades?

💡 Explanation

Decreased capacitance from capacitor degradation causes reduced shock energy through impedance mismatch; the capacitor's ability to store charge diminishes. This outcome occurs because stored energy is a function of capacitance; therefore shock output decreases rather than any alternative arrythmia-related consequences.
