We describe a patient whose presentation of ICD generator failure was excruciating shoulder pain lasting 3 hours. This painful episode prompted evaluation and subsequent generator replacement. Destructive analysis of the explanted device revealed a short circuit of three battery filter capacitors, which resulted in the battery "dumping" its full energy very rapidly, since the impedance across the battery terminal was < 1 ohm. The duration of the painful episode was equal to the estimated ICD battery life under this low impedance condition.
