A transesophageal defibrillating system includes a large area anterior patch electrode and a large area posterior patch electrode, as in some conventional exterior defibrillating systems. An esophageal probe has a pair of ring electrodes, one of which is carried at or near its distal end. The system is operatively arranged to supply defibrillation pulses between the large anterior patch electrode and either the distal electrode (carried by the probe) or the large posterior electrode, depending on which one of the latter two electrodes is connected or coupled by the clinician or paramedic to the defibrillating pulse source. The system includes a source of pacing pulses which may be supplied to the patient via the anterior patch electrode and at least one of the electrodes carried by the esophageal probe. The distal electrode is believed to be the more effective electrode to use for this purpose. The system also preferably provides for sensing, displaying and recording ECG signals, the two electrodes carried by the probe supplying input representing electrical activity of the heart for display and/or recording.
