Figure 5From: Reduced Ca2+ transport across sarcolemma but enhanced spontaneous activity in cardiomyocytes isolated from left atrium-pulmonary veins tissue of myopathic hamsterTransient outward K+ current (I TO ) activated on depolarization in healthy (panel A) and myopathic LA-PV myocytes (panel B). Clamp protocol is shown on top of panel B. The mean current-voltage relations of ITO in 23 healthy (closed circles) and 17 myopathic myocytes (open circles) are shown in panel C.Back to article page
