Title:
ELECTRICAL DEVICE FOR INTRACARDIAC DEFIBRILLATION, INTRACARDIAC DEFIBRILLATION CATHETER SYSTEM, AND METHOD FOR INSPECTING ELECTRICAL DEVICE FOR INTRACARDIAC DEFIBRILLATION
Document Type and Number:
WIPO Patent Application WO/2021/251033
Kind Code:
A1
Abstract:
Provided is an electrical device (1) for intracardiac defibrillation, having: a capacitor (2) for accumulating charge; a load resistor Rb, which is electrically connected to the capacitor (2) and to which a discharge current from the capacitor (2) flows, and which moreover has a resistance value higher than 50 Ω; a measurement unit (3) for acquiring the voltage of the capacitor (2), the measurement unit (3) being electrically connected to the capacitor (2); and an estimation unit (5) for using the voltage value of the capacitor (2) after the capacitor (2), having accumulated a prescribed charge, discharges to the load resistor Rb, to calculate the discharge energy occurring in cases where the capacitor (2), having accumulated a prescribed charge, discharges to a prescribed simulated resistor Ra that has a resistance value lower than that of the load resistor Rb and that simulates a human heart.
