| Abstract: | The occurrence of inappropriate discharge from an implanted cardioverter-defibrillator is reported. The device was triggered by an episode of induced nonsustained ventricular tachycardia, and the shock was delivered 10 sec after spontaneous termination of the arrhythmia. This observation demonstrates that unexpected discharges from an implanted cardiaverter/defibrillator can occur while the patient is asymptomatic. In order to avoid such an adverse effect, improvement of the detection system of the device is advisable. |
