Abstract: Provided are a defibrillation catheter system, a defibrillation power supply device, and a method for controlling the device during observation of intracardiac potential and defibrillation. A defibrillation catheter system 1 includes a catheter 20; a power supply part 6 connected to the catheter 20; an electrocardiograph 40 measuring an intracardiac potential; a first electrode 21 and a second electrode 22 provided on the catheter; and a changeover part 7 connected to the power supply part 6, the changeover part 7 switching between a first mode for measuring the intracardiac potential and a second mode for applying the voltage while the intracardiac potential is measured, wherein the first electrode 21 and the second electrode 22 are connected to the power supply part 6 through the changeover part 7, and the first electrode 21 and the second electrode 22 are connected to the electrocardiograph 40.
