ABSTRACT:
A defibrillation electrophysiology catheter for stimulating the heart and sensing the resulting activity of the heart for determining a patient's potential to have an arrhythmia occur under uncontrolled circumstances and for defibrillating the heart if fibrillation occurs accidentally during the testing is disclosed. The catheter is provided with electrodes formed on the distal surface of the catheter which is placed near the patient's heart. The electrodes may be placed on the catheter in a variety of configurations. An external electrode in the form of a patch or pad is placed on the patient's back. Energy is applied to the system in order to shock the heart and defibrillate the same. The procedure is less invasive than the procedures requiring the electrodes to be implanted at or near the patient's heart and chest wall and requires less energy and time than the procedures requiring the use of two external paddles.
