AAMI EC11-91

Establishes minimum safety and performance requirements for electrocardiographic (ECG) systems with direct writing devices which are intended for use in the analysis of rhythm and of detailed morphology of complex cardiac complexes. Subject to this standard are all parts of the electrocardiographic system necessary to obtain the signal from the surface of the patient’s body, to amplify this signal, and to display it in a form suitable for diagnosing the heart’s electrical activity. This standard defines requirements for the electrocardiographic recording system, from the input electrodes to the output display.
