ECG100+ - ECG200+ - ECG100S - ECG200S
13. TECHNICAL SPECIFICATION
13.1. Filter features
The device adopts different filtering techniques in order to process the signal and make it easier for the
cardiologist to make the diagnosis.
The device implements a high-pass linear-phase filter, with a cutoff frequency of 0.67Hz, to remove the drift
of the entirely digital baseline.
The filter effectively reduces the artefacts induced by the respiratory movement without introducing
distortions on the reproduction of the ST segment, as specifically recommended in "cf. Paul Kligfield et al.,
Recommendations for the Standardization and Interpretation of the Electrocardiogram Part I, Circulation.
2007;115:1306-1324ā:
To reduce artifactual distortion of the ST segment, the 1990 AHA document recommended that the
low-frequency cutoff be 0.05 Hz for routine filters but that this requirement could be relaxed to 0.67
Hz or below for linear digital filters with zero phase distortion. The ANSI/AAMI recommendations of
1991, affirmed in 2001, endorsed these relaxed limits for low-frequency cutoff for standard 12-lead
ECGs, subject to maximum allowable errors for individual determinants of overall input signal
reproduction. These standards continue to be recommended
The high-pass filter meets the requirements set by IEC 60601-2-25 2nd Ed. in terms of low-frequency
impulse response:
