delayed electrical activity in ischemically injured ventricular myocardium produced by premature ventricular stimuli ( mean +/- sd = 179 +/- 34 ms ) was delayed further by the administration of lidocaine ( 237 +/- 42 ms , p less than 0.01 ) , resulting in continuous local electrical activity between the final premature ventricular stimulus and the initial beat of the resultant ventricular tachycardia .
