Advances understanding of cardiac membrane currents in animal models; leaves open translation to human electrophysiology.
This basic electrophysiology study characterized the time-dependent components of membrane currents in cat ventricular fibers, identifying specific inward and outward components.
McDonald et al. (1978) studied this question. Membrane potential depolarization was evaluated on Membrane current components. Membrane currents in cat ventricular fibres on depolarization contained three time-dependent components attributable to the inactivation of slow inward current and activation of two outward currents.
