DEBATE ON THE IONIC BASIS of automaticity in the sinoatrial node (SAN) has persisted since the onset of the field of cardiac cellular electrophysiology, with the favored theory replaced or refined periodically (see Refs. 1, 16, 17, 21, 24–26). For many years, the accepted concept was that of a decaying repolarizing K current (IK2) against the background of… CONTINUE READING
