Control method of defibrillation catheter system, defibrillation power supply and defibrillation power supply

摘要

A defibrillation catheter system, a defibrillation power supply device, and a control method for the device, which can observe the intracardiac potential and easily control the system even during defibrillation as in the case of intracardiac electrocardiogram measurement. provide. A catheter 20 extending in the perspective direction, a first power supply unit 6A and a second power supply unit 6B connected to the catheter 20 and generating an applied voltage, an electrocardiograph 40 for measuring an intracardiac potential, and an electrocardiograph 40. The defibrillation catheter system 1 having the first electrode group 21 having at least 1-1 electrodes 21A and 1-2 electrodes 21B on the distal side of the catheter 20 and the first electrode group 21. A second electrode group 22 having at least a second electrode 22A and a second electrode 22B arranged on the proximal side is provided, and the first electrode group 21 and the second electrode group 22 are provided. , The 1-1 electrode 21A and the 2-1 electrode 22A are connected to the first power supply unit 6A, and are connected to the electrocardiograph 40 without going through the switch unit. The 2-2 electrode 22B is connected to the second power supply unit 6B.
