(A) Time-dependent effects of distilled water (DW) 0.1% and of Quinidine at 10 µM on the action potential at 1 Hz (one Purkinje fiber representative of three). (B) Effects of distilled water (DW) 0.1% and of Quinidine at 10 µM on the four action potential parameters at 1 Hz (Data are expressed as mean ± SEM, n = 3 Purkinje fibers).
