Survival according to ejection fraction

	EF >35%		EF ⩽35%
Survival/event-free interval	6 months	24 months	6 months	24 months
Overall mortality	87.4%	75.9%	93.3%	77.0%
Cardiac death	92.2%	80.0%	93.3%	77.0%
Sudden death	97.8%	89.7%	100%	94.7%
VT	58.9%	34.7%	57.3%	26.5%
Fast VT	85.0%	76.9%	85.3%	67.7%

Actuarial survival rates and intervals free of recurrence of ventricular tachycardia in relation to ejection fraction (cut off value 35%). There were no significant differences between subgroups.

EF, ejection fraction; fast VT, ventricular tachycardia of ⩾240 beats/min; VT, ventricular tachycardia.
