Appendix I ECG Automated Measurement&Interpretation Guide
1. Preface
The appendix describes the functions of ECG automated measurement and automated
interpretation. It explains the specific implementation method, algorithm and formulas related to
these two functions, as well as the content output by the automated measurement and automated
interpretation.
According to the requirement of IEC60601-2-51:2003 Medical electrical equipment - Part
2-51: Particular requirements for safety, including essential performance, of recording and
analysing single channel and multichannel electrocardiographs, Clause 50 Accuracy of
operating data, the appendix gives a description of verification process and results of the
performance for automated measurement and automated interpretation.
