De. Mann et al., INAPPROPRIATE SHOCK THERAPY FOR NONSUSTAINED VENTRICULAR-TACHYCARDIA IN A DUAL-CHAMBER PACEMAKER DEFIBRILLATOR, PACE, 21(10), 1998, pp. 2005-2006
We report a patient who received a CPI Ventak AV II DR TCD for ventric
ular tachycardia and complete heart block without an escape rhythm. Du
ring induced nonsustained ventricular tachycardia, the device, althoug
h programmed to deliver noncommitted shocks, acted like a committed de
vice. This phenomenon is due to undocumented behavior that is likely t
o occur in any patient who is pacemaker dependent and has nonsustained
ventricular tachycardia.
