Università Campus Bio-Medico di Roma via Alvaro del Portillo, 21, Rome

ABSTRACT It is important to recognize that high fidelity in the reproduction of the ECG waveform requires a measurement system that preserves the ECG features and provides amplification selective to the physiological signal while rejecting external interference and noise. The most obvious implication is that the presence of a frequency-dependent skin-electrode interface introduces distortion to the signal in its propagation from its source to the input of the recording amplifier, which may lead to misdiagnosis of serious cardiac conditions unless…
