Recovery of the slow inward current from Ca2(+)-mediated and voltage-dependent inactivation in the rabbit sinoatrial node.


The process of recovery from inactivation of the slow inward current (isi) in the rabbit sinoatrial (S-A) node was evaluated by voltage clamp experiments using double microelectrode method. Double pulse experiments were carried out on preparations loaded with Cs+ using nystatin. The rate of the rapid isi inactivation depended on the amplitude of isi rather… (More)
