VENTRICULAR FIBRILLATION PREVENTING DEVICE AND VENTRICULAR FIBRILLATION REMOVING DEVICE

摘要

[PROBLEMS] To prevent an occurrence of ventricular fibrillation [MEANS FOR SOLVING PROBLEMS] A rectangular substrate 10 is sewn onto the epicardial surface of a left ventricle 38. Four cooling Peltier elements 12 are provided at the center of the substrate 10, and temperature-detecting thermistors 18 are provided at part of their peripheries. Multiple circular and flat potential sensors/stimulating electrodes 14 for detecting the surface potential of the heart are arranged in a lattice form on the surface of the substrate 10 at almost equal intervals. The potential sensors/stimulating electrodes 14 are stimulating electrodes for delivering a pulse voltage/current to the heart. When ventricular tachycardia is detected, power is applied to these Peltier elements 12 to cool the heart. If the cooling cannot stop ventricular tachycardia, a pulse voltage/current is delivered via the multiple potential sensors/stimulating electrodes 14 to eliminate ventricular tachycardia at a low voltage to prevent ventricular fibrillation.
