Abstract

There exist two types of voltage gated Ca channels in cardiac cells [1–3]. The literature describing the biophysics and physiology of these channels, the L type Ca channel (iCaL) and the T type Ca channel (iCat), is vast. It is not the intent of this chapter to review this exhaustive literature; however, initially we describe some of the physiological and biophysical facts essential for the study of channel pharmacology. On the other hand, the literature describing the pharmacology of these two cardiac Ca channels is limited, particularly in reference to the pharmacology of the T type channel. Therefore, the emphasis here is to discuss the known pharmacology of both channels with particular attention to the T type Ca channel.
