Abstract
A transvenous cardioversion lead for use in standby cardioversion in patients who have a high risk of ventricular tachycardia or fibrillation, adapted for use with presently available external defibrillation units. The lead is provided with energy-reducing or energy-limiting circuitry to prevent the inappropriately high energy levels which may be generated by external defibrillation units from causing injury to the patient while preserving the beneficial waveform of the defibrillation pulse. The lead is further provided with at least three electrodes, two for location in the ventricle, at least one for location in the superior vena cava. The lead is so constructed that the superior vena cava electrode and one of the ventricular electrodes may be used for cardioversion, while the two ventricular electrodes may be used for cardiac pacing and sensing.
