Apparatus for recognition and termination of ventricular tachycardia and ventricular fibrillation










Image Number 2 for United States Patent #4790317.

For automatic recognition of ventricular tachycardia and ventricular fibrillation, pulse sequences are compared 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 a next pulsing at that same position will indicate both ventricular tachycardia and ventricular fibrillation so as to enable a response to be made to restore a pulse sequence representing normal ventricular activity of the heart.
