lidocaine and tocainide had no effect on ventricular conduction of extrasystoles with coupling intervals longer than 500 msec in isolated blood-perfused dog hearts , but caused interval-related increases in conduction time of extrasystoles in the range of 250 -- 400 msec , here called mid-range extrasystoles ( mre ) .
