METHOD FOR IDENTIFYING ACTIVE SITE OF VENTRICULAR TACHYCARDIA (VT) AND CATHETER REMOVING DEVICE FOR ATTACHING ELECTRODE OF CLOSELY OPERABLE DEVICE FOR REMOVING ENDOCARDIUM

摘要

PURPOSE: To provide a system for removing arrhythmia guided electrophysiologically for ventricular tachycardia or other arrhythmia. CONSTITUTION: An active site characterized by having a process (a) measuring the diastole interval of the heart, a process (b) mapping heart tissue for the active site, a process (c) specifying the active site in 20-80%, pref., 35-50% of the diastole interval and a process (d) attaching the electrode of a defibrillator to the active site and activating the diastole during ventricular tachycardia(VT) for attaching the electrode of defibrillator is specified. When an apparatus is in an active site state, a removing (ablation) energy source is triggered and, when the apparatus is not there, the opening of latently harmful energy is prohibited.
