TRANSPLANTABLE ATRIUM-ELECTRIC GRADUAL FIBRILLATION DEVICE, ELECTRIC GRADUAL FIBRILLATION/FIBRILLATION REMOVING DEVICE, TRANSPLANTABLE ATRIUM TACHYCARDIA ELECTRIC GRADUAL FIBRILLATION DEVICE, AND OPERATING METHOD FOR TACHYCARDIA ELECTRIC GRADUAL FIBRILLATION DEVICE

摘要

PURPOSE: To provide a method and device capable of being transplanted for automatic sensing of atrium arrhythmia and the low-energy atrium-electric gradual fibrillation remedy requiring minimum tissue damage. ;CONSTITUTION: An atrium-electric gradual fibrillation device, etc., according to the present invention capable of being transplanted is installed in an automatic pace maker fibrillation remover/electric remover for the high-energy ventricular fibrillation removing remedy, double chamber anti-tachycardia pacing remedy, and slow pulsation support pacing. Each of them consists of three-electrode atrium and ventricle intra-heart membrane leads 150 and 151 including a chip, ring pacing electrode, and polar electric gradual fibrillation electrode and is used together with a hypodermic electrode lead 152 to treat a patient where it is not needed to open the thoracic cavity owing to the transplanting possibility. From the four transplanted electrodes, a number of electric gradual fibrillation electrode arrangements can be selected, and if no electric gradual fibrillation is not attained by the first arrangement, an automatic switch changes over to another electrode arrangement is adopted.;COPYRIGHT: (C)1993,JPO
