Fast activation of cardiac Ca++ channel gating charge by the dihydropyridine agonist, BAY K 8644.

Nonlinear charge movement (gating current) was studied by the whole-cell patch clamp method using cultured 17-d-old embryonic chick heart cells. Na+ and Ca++ currents were blocked by the addition of 10 microM TTX and 3 mM CoCl2; Cs+ replaced K+ both intra- and extracellularly. Linear capacitive and...
