Apparatus for recognition of ventricular tachycardia and ventricular fibrillation and for termination thereof.

摘要

Apparatus for the automatic recognition of ventricular tachycardia and ventricular fibrillation compares pulse sequences which are obtained when sensing at at least one position on each ventricular epicardial surface of a heart. Changes in the sequence of activations and in the timing from pulsing at one sensor position to next pulsing at that position will indicate both ventricular tachycardia and ventricular fibrillation to enable a response to be made to restore to a pulse sequence representing the normal ventricular activity of the heart.
