in order to identify defects in na+-ca2+ exchange and ca2+-pump systems in cardiomyopathic hearts , the activities of sarcolemmal na+-dependent ca2+ uptake , na+-induced ca2+ release , atp-dependent ca2+ uptake and ca2+-stimulated atpase were examined by employing cardiomyopathic hamsters ( um-x7.1 ) and catecholamine-induced cardiomyopathy produced by injecting isoproterenol into rats .
