<P>PROBLEM TO BE SOLVED: To provide an intracardiac defibrillation catheter system capable of reliably supplying electric energy necessary and sufficient for defibrillation, and being used as an electrode catheter for cardiac potential measurement while defibrillation treatment is not performed. <P>SOLUTION: An intracardiac defibrillation catheter system includes a defibrillation catheter 100, a power source device 700, and an electrocardiograph 800. The defibrillation catheter 100 has a first DC electrode group 31G and a second DC electrode group 32G; and the power source device 700 has a DC power source unit 71, a catheter-connected connector 72, an electrocardiograph-connected connector 73, an arithmetic processing unit 75 which controls the DC power source unit 71 and comprises an output circuit 751 for outputting a DC voltage supplied from the DC power source unit 71, and a switch 76 wherein the catheter-connected connector 72 is connected to a common contact, the electrocardiograph-connected connector 73 is connected to the first contact, and the arithmetic processing unit 75 is connected to the second contact. <P>COPYRIGHT: (C)2011,JPO&INPIT |
