IEC 60601-2-51:2003

Establishes particular requirements, in addition to the requirements of IEC 60601-2-25, for the safety, including essential performance of recording and analysing single channel and multichannel electrocardiographs.

These requirements shall apply particularly to

- recording electrocardiographs;

- electrocardiographs which are part of other medical electrical equipment, for example exercise testing systems, if this equipment is used to record ECGs for diagnostic purposes;

- electrocardiographs which are used as output units for ECG data base management systems or electrocardiographs which are used as output units located at other places than the recording unit;

- analyzing electrocardiographs, systems, and computing devices which by means of electronic data processing and pattern recognition derive measurements (e.g. intervals and amplitudes) and diagnostic statements from the ECG;

- those parts of patient monitors or other specialised electrocardiographs that are capable of performing the functions of the analyzing electrocardiographs.
