Webtherefore examined the effects of membrane depolarization and low intracellular pH on the t-tubular charge movement. Fibers were voltage clamped in a double Vaseline gap, at holding potential (HP) of 290 or 260 mV, and studied at an internal pH of 7.0 and 6.2. Decreasing intracellular pH did not significantly alter the maximum amount of charge Web31 jan. 2024 · Ischemic depolarization of the AV node can depress conduction and cause AV blocks primarily by inactivation of L-type Ca ++ channels , which are responsible for phase 0 depolarization in nodal tissue. Key concepts: cardiac ischemia causes. increased extracellular K + and a less negative E K; myocyte depolarization;
WebUnder the influence of cardiotonic steroids, single ventricular cells exhibit transient depolarization after a train of driven action potentials or, in voltage clamp experiments, transient inward current after a depolarizing clamp pulse. WebThe length constant is the distance over which the magnitude of the depolarization falls to a value of 1/e (e = 2.718) of the initial depolarization. The length constant for a small neuron with a large number of resting K+ channels (black curve) can be as small as 0.1 mm; in this example it is about 0.5 mm.
