The first-order high-pass filter influences the automatic measurements of the electrocardiogram

We have studied the effects of the 0.05 Hz first-order high-pass filter (AC coupling) on the automatic measurements of the electrocardiogram (ECG). The standard 12-lead ECG of 1248 patients and the automated measurements of the AC-and DC-coupled (unfiltered) versions were compared. We found a strong…
