Depolarization and action potential duration in cardiac Purkinje fibers.
The effect of depolarization on the duration of the action potential was studied in short cardiac Purkinje fibers. Membrane potential was altered by overdriving pacemaker fibers showing spontaneous diastolic depolarization (dog), by injecting constantcurrent pulses through an intracellular microelectrode (sheep), or by voltage clamping (dog). Test action potentials were elicited at the end of 5...

متن کاملMechanisms of Action of Lidocaine and Quinidine on Action Potential Duration in Rabbit Cardiac Purkinje Fibers
The effects of lidocaine and quinidine on rabbit cardiac Purkinje fibers were compared at 37 °C, using action potential and voltage clamp measurements. At therapeutic concentrations (5 /ig/ml), lidocaine shortened the duration of the action potential while quinidine lengthened it. When membrane potential was held constant between —40 and —50 mV by the application of the two-microelectrode volta...
متن کاملControl of action potential duration by calcium ions in cardiac Purkinje fibers
It is well known that cardiac action potentials are shortened by increasing the external calcium concentration (Cao). The shortening is puzzling since Ca ions are thought to carry inward current during the plateau. We therefore studied the effects of Cao on action potentials and membrane currents in short Purkinje fiber preparations. Two factors favor the earlier repolarization. First, calcium-...
متن کاملAction Potential Duration Alternans in Dog Purkinje and Ventricular Muscle Fibers
An abrupt shortening of cycle length causes action potential duration (APD) alternation in both canine Purkinje (P) and ventricular (V) muscle fibers. Our recent study suggested that APD alternans is determined by the process controlling APD during electrical restitution in P but not in V fibers. In the latter, alternans was attributed to changes in the availability of intracellular calcium [Ca...
