High-Bandpass Filters in Electrocardiography: Source of Error in the Interpretation of the ST Segment

<table>Alterations in the ST segment in the presence of left bundle block. In autorecording mode and regardless of the high-pass filter used, the shape of the ST segment was not affected. On the other hand, 0.5 Hz high-pass filters in manual mode caused a considerable elevation of the ST segment in V1–V3. Auto and manual mode (see Figure <a href="../fig3/">3</a>).</table>
