the signal-averaged qrs complex was significantly longer in dogs with inducible ventricular tachycardia or fibrillation ( 61 +/- 5 versus 57 +/- 3 ms , p = 0.02 ) , had a lower terminal qrs amplitude ( 24 +/- 20 versus 46 +/- 33 microv , p = 0.04 ) and a longer late potential duration ( 19 +/- 4 versus 15 +/- 3 ms , p = 0.003 ) compared with that in animals with no inducible ventricular arrhythmia .
