Key result
Repeated intraoperative inductions of VT/VF during ICD implantation in patients with severe LV dysfunction did not significantly alter cardiac index (1.9 vs 2.1 L/min/m2; NS).

May reassure on acute hemodynamic stability during ICD testing in severe LV dysfunction; hypothesis-generating and should not yet change protocols.
Observational (n=11)
Does repeated intraoperative induction of VT/VF during ICD implantation reduce cardiac output in patients with severe left ventricular dysfunction?
Absolute Event Rate: 2.1% vs 1.9%
p-value: p=NS
Extensive defibrillation testing during ICD implantation in patients with severe LV dysfunction does not cause acute deterioration of cardiac performance.
Meyer et al. (1996) conducted an observational in Severe left ventricular dysfunction (n=11). Repeated intraoperative inductions of ventricular tachycardia/fibrillation (VT/VF) vs. Pre-induction baseline was evaluated on Cardiac index (p=NS). Repeated intraoperative inductions of VT/VF during ICD implantation in patients with severe LV dysfunction did not significantly alter cardiac index (1.9 vs 2.1 L/min/m2; NS).
