 border=0 align=center>Application Notes | Technical Articles | Ask the Experts An ECG (EKG) measures the electrical activity of a patient’s heart. Treated as a vector quantity, the cardiac signal, typically 1mV, is measured differentially. The first stage provides low gain to amplify the magnitude of the cardiac vector. Initial gain is limited by the 500mV DC offset that develops between leads. A band pass filter of 0.05Hz to 150Hz is employed. After the ADC, the signal is passed through a galvanic isolation barrier.
