univariate predictors of appropriate aicd discharge included depressed left ventricular ejection fraction ( p = 0.0007 ) , inducible sustained ventricular arrhythmia at electrophysiologic study performed in the absence of antiarrhythmic drugs ( p = 0.009 ) , fewer number of extrastimuli required for induction at this study ( p = 0.001 ) , inducible sustained arrhythmia at electrophysiologic study performed on the discharge antiarrhythmic regimen ( p = 0.0005 ) and fewer extrastimuli required for this induction ( p less than 0.0001 ) .
