1. Prolongation of action potentials upon the addition of isoproterenol, forskolin, isobutylmethyl-xanthine (IBMX) and dibutyril cAMP (dbcAMP) under Ca-free EGTA condition was examined in isolated myocardial preparations from neonatal and adult rats, whose action potential configuration greatly differ. 2. The prolongation of the action potential was… CONTINUE READING
