High-Bandpass Filters in Electrocardiography: Source of Error in the Interpretation of the ST Segment
Aman Thind on Twitter: "4/ Technically speaking, wall filter is a 'high-pass filter'. It's a generic category of electronic filters that filters out lower frequencies (allows the higher frequencies to 'pass'). E.g. -
