WebJan 3, 2024 · To briefly recap the physiology of L-type calcium channels: L-type calcium channels are voltage-gated calcium channels, which open (slowly) at a threshold membrane potential of around -30 mV, and conduct a calcium current into the cell In the cardiac muscle, these account for the Phase 2 plateau of the normal cardiac action potential. The L-type calcium channel (also known as the dihydropyridine channel, or DHP channel) is part of the high-voltage activated family of voltage-dependent calcium channel. "L" stands for long-lasting referring to the length of activation. This channel has four isoforms: Cav1.1, Cav1.2, Cav1.3, and Cav1.4.
