moreover , there was no difference in either the pattern of arrhythmia initiated in each of the pacing modes with respect to ventricular tachycardia versus ventricular fibrillation , or in the median current required to initiate ventricular tachycardia ( 0.30 +/- 0.36 ma ) versus ventricular fibrillation ( 0.31 +/- 0.44 ma ; p greater than 0.1 ) .
