Abstract :
Electrocardiography (ECG) monitoring during electrosurgery may become greatly distorted from the interference of the radio-frequency (RF) signals generated by the electrosurgical unit. A solution to this problem is discussed. In the ECG sampling unit the RF function generator used to drive an RF power amplifier for the cutting signal for the wand is controlled in such a way that a sample of the ECG is taken while the generator is off. This is done without significantly altering the cutting signal
