PROBLEM TO BE SOLVED: To quickly and appropriately execute the interruption treatment of an abnormal conductive route by sensing two electric signals by means of a probe which is arranged in a treatment site of a heart, deciding the correlative mensuration values of the two sensed signals and detecting the abnormal conductive route of the treatment site. SOLUTION: A control unit 22 is connected to the base end part of a catheter 20 to be inserted to the heart and, in the meantime, an excision device 26, two electrodes 28 and 30 for sensing an electric exciting signal in an endocardium and a localization sensor 32 are arranged in the neighborhood of a tip part 24. Then, the output signals of the electrodes 28 and 30 and the localization sensor 32 are inputted to a signal analyzer circuit 36 in the control unit 22. In the circuit 36, the correlative coefficient of first and second signals before excision is decided by the execution of time-region correlative calculation where a first excision signal is multiplied by the second one and the product is integrated over more then one cardiac period and, then, the abnormal conductive route of the treatment site is detected based on the correlative mensuration value. |
