Transmembrane potential changes caused by monophasic and biphasic shocks

Transmembrane potential changes caused by monophasic and biphasic shocks

Transmembrane potential change (Delta Vm) during shocks was recorded by a double-barrel microelectrode in 12 isolated guinea pig papillary muscles. After 10 SI stimuli, square-wave S2 shocks of both polarities were given consisting of 10-ms monophasic and 10/10-ms and 5/5-ms biphasic waveforms that...

Zusammenfassung:Transmembrane potential change (Delta Vm) during shocks was recorded by a double-barrel microelectrode in 12 isolated guinea pig papillary muscles. After 10 SI stimuli, square-wave S2 shocks of both polarities were given consisting of 10-ms monophasic and 10/10-ms and 5/5-ms biphasic waveforms that created potential gradients from 1.1 +/- 0.3 to 11.9 +/- 0.4 V/cm.
