A catheter capable of simultaneously measuring the action potential of myocardiac cells by means of a pair of electrodes, and the endocardiac cavity pressure by means of a pressure transducer. One electrode is provided to the enclosing front surface of a catheter body when the catheter body is brought into contact with the endocardiac surface guided into the endocardiac cavity. The other electrode is provided to the distal peripheral surface of the catheter body and is disposed within the endocardiac cavity when the catheter is guided into the endocardiac cavity and the other electrode contacts the endocardiac surface. The pressure transducer is provided to the peripheral surface of the distal section, for measuring the endocardiac cavity pressure and outputting it in the form of an electrical pressure signal. Lead wires are connected to the pair of electrodes and the pressure transducer, and are guided from the rear section of the catheter body in order to transfer the measured action potential and electrical pressure signals, from the catheter body, to processing and display equipment.
