PROBLEM TO BE SOLVED: To measure an electrocardiogram(ECG) while burning the diseased part with high frequency. SOLUTION: Electrodes 2 and 3 are arranged on the top end side of a catheter 1. One electrode 2 is connected to a high frequency generator 11. These electrodes 2 and 3 are respectively connected through lead wires 4 and 5 to an intraheart ECG recorder 22. The lead wires 4 and 5a are provided with a signal separating means 18 having a low-pass filter circuit 33. With this signal separating means 18, high frequency signal components from the high frequency generator 11 can be separated. Then, the ECG can be recorded simultaneously with burning due to the high frequency. |
