Abstract
AN investigation of the influence of driving stimuli on the membrane action potentials of toad cardiac muscle fibres has been made. Endocardial surfaces of excised hearts were exposed and the transmembrane potentials of atrial and ventricular fibres recorded by means of glass-pipette microelectrodes.
