Conduction velocity measurements. A and B: epicardial isochronal maps generated from optically mapped guinea pig hearts perfused with increasing potassium concentrations. Transverse (CVT) and longitudinal (CVL) conduction velocity designated for visualization purposes. C and D: summary of CVT (C) and CVL (D) as a function of potassium concentration. Adapted from Ref. 115 with permission. *P < 0.05, significantly different compared with 4.6 mM K+.
