five seconds after tachycardia induction , hemodynamically stable ventricular tachycardia had a longer cycle length ( 294 +/- 41 ms ) and the right ventricular pulse pressure ratio was higher ( 0.55 +/- 0.26 ) than that in unstable ventricular tachycardia ( cycle length 256 +/- 55 ms , p = 0.06 ; pulse pressure ratio 0.26 +/- 0.09 , p less than 0.05 ) .
