Abstract

It is now recognized that calcium channels exist in a wide variety of cells and participate in many aspects of cellular function (for review, see refs. 1 and 2). In the heart, voltage-dependent calcium ion influx underlies spontaneous activity and impulse conduction in the sinoatrial and atrioventricular nodes, maintains the plateau phase of ventricular action potentials, and is closely associated with activation of contraction (3–6). Thus, it is not surprising that compounds which block calcium channels are of considerable interest to cellular electrophysiologists and, in particular, to those interested in the electrophysiology of the heart.
