Comparison of early afterdepolarization induced by cesium chloride in mouse atrial and ventricular fibers.


AIM To study the similarities and the differences in the induction of early afterdepolarization (EAD) by CsCl, a blocker of potassium channels, between mouse atrial and ventricular fibers. METHODS Papillary muscle from left ventricle or a small piece of right atrium of Swiss Albino mouse was isolated. Transmembrane action potential (AP) and EAD were… (More)
