antiarrhythmic and cardioprotective effects of propranolol and sotalol were examined by studying their action on cellular electrical activity ( recorded using standard microelectrode techniques ) and creatine-kinase leakage ( measured in the effluent from the experimental bath chamber ) in the in vitro guinea-pig left ventricular myocardium exposed to conditions mimicking severe or moderate ischemia .
