those with ventricular tachycardia had a greater prevalence of : more complex ventricular arrhythmia on 24 hour electrocardiogram ( 63 versus 0 % , p less than 0.001 ) , long his bundle to ventricle interval ( 44 versus 0 % , p less than 0.001 ) , right ventricular systolic pressure of 70 mm hg or more ( 56 versus 0 % , p less than 0.01 ) and reduced right ventricular ejection fraction ( 33 versus 7 % , p less than 0.025 ) .
