[Rest and active potentials of dissociated rat heart cells in culture].
Intracellular investigation of bioelectrical properties is performed on cultivated rat myocardial cells. Electrophysiological parameters of cells dissociated from rat myocardium are very similar to those of in vivo cells. Fast sodium channels are found to be fonctional. Spontaneous arrhythmia are recorded from some impaled cells.
