Summary

The aim of this review is to present the key role of the slow component of the delayed rectifier potassium current (IKs) and the repolarization reserve in large mammalians including human ventricle. The review gives a detailed historical description about how our group identified and gave the first experimental demonstration about the cardiac repolarization reserve. The authors also present the role of the IKs current in the human cardiac repolarization and repolarization reserve focusing on several pathophysiological situations, such as genetic diseases (for example LQT syndromes), diabetes mellitus, congestive heart failure and the serious lethal ventricular arrhythmias (for example Torsade de Pointes cardiac arrhythmias).
