title = "Effect of Electrode Impedance on the Transient Response of ECG Recording Amplifiers",
abstract = "The transient response of ECG amplifiers is investigated in the light of the IEC 60601 performance standard for ECG recording equipment. Simulations carried out using models of several modern electrodes reveal that the undershoot limit of 100 μV and the recovery slope limit of 300 μVs-1 in response to a narrow 3 mV-100 ms rectangular pulse are violated when the recommended input impedance of 10 MΩ and a high-pass cut-off frequency of 0.05 Hz are used in the amplifier. Signal distortions have been observed which have clinical diagnostic implications. The results suggest that an amplmer input impedance exceeding 1 GΩ and a cut-off frequency somewhat lower than 0.05 Hz are necessary in order to meet the IEC 60601 performance criteria and avoid distortion of the recorded ECG signal. The authors therefore recommend that future revisions and releases of the IEC 60601 standard should include an electrical model for the skin-electrode interface in the transient response specification.",
