Product description:For membrane inhibitory anti-arrhythmic drugs, that can be applied directly to the myocardial cell membrane, can significantly extend the myocardial refractory period, reduce the self-discipline, conductivity and myocardial contraction force, especially of the sinus ectopic rhythmic effect is stronger, the action potential of time constant on the sinoatrial node cells or extended, reduce conduction velocity, extend the effective refractory period, reduce excitability, in atrial refractory period extended from ventricular, shorten the atrioventricular border refractory period.
