Physiological monitoring electrode system

摘要: A monitoring electrode system is provided in which just two electrodes and their corresponding lead lines may be utilized for a unit, such as an ECG, having three input terminals normally requiring signals from electrodes. To achieve system, body tissue impedance simulating circuit included to provide automatic reference line signal at the third terminal. Protection against high voltages radio frequency interference by various circuits, voltage protection circuit, low pass filter network or RF choke network. In preferred embodiment hereof, pair of are with connecting plug engages connector end cable extending ECG monitor. Preferably, any protective circuits located cable.
