Mechanisms of Arrhythmogenesis

Arrhythmias If a microelectrode is introduced into a single myocardial cell, an action potential (Figure 1) can between the inside and the outside of the cell (inside negative). The resting membrane potential of a normal Purkinje cell is approximately – 90 millivolts (mv) with respect to the outside of the cell. When the membrane potential … Continue reading “Mechanisms of Arrhythmogenesis”
