OBJECTIVE The goals of this study were to identify the types of outward potassium (K+) currents that are activated at membrane potentials corresponding to the plateau of the action potential in human atrial myocytes, and to compare their properties with published data describing the K+ channels which have been cloned from a human cDNA library. METHODS Specimens of right atrial appendages were obtained from patients undergoing cardiac surgery. Single myocytes were isolated enzymatically and… CONTINUE READING
