Single pacemaker cells were isolated from the sinus venosus of cane toad ... However it is widely believed that frog heart does not contain a . Identification of the pace-maker current in frog atrium. Ionic mechanisms of adenosine actions in pacemaker cells from. The fine structure and electrophysiology of heart muscle cell injury.. of adrenaline on membrane currents underlying pacemaker activity in frog atrial muscle. Transitional cells of intermediate complexity (e.g., subsidiary pacemaker cells) are interposed between these two types of cardiac cells. This study focuses .
