SYSTEM AND METHOD FOR EVALUATING DEMAND REFERENCE OF INDUCED DEFIBRILLATION OF DEVICE IMPLANTED WITHOUT REPEATED INDUCTION OF FIBRILLATION

摘要

PROBLEM TO BE SOLVED: To provide a system which determines an effective fibrillation energy released into an implanting fibrillation system without the repeated induction of the fibrillation in the heart of a patient.

SOLUTION: The system herein disclosed determines the defibrillation threshold energy in the defibrillation induction structure by applying shocks to the heart until the heart undergoes the fibrillation state while lowering the energy level during the T wave period in the electrocardiogram. The lowest energy level of those examined that fail to make the heart undergo the fibrillation state is mutually related to the defibrillation threshold energy in the induction structure.
