Medical informatics - Standard communication protocol - Computer-assisted electrocardiography ENV 1064:1993

Scope

The present Standard relates to the conventional recording of the electrocardiogram , i.e. the socalled standard 12-lead electrocardiogram and the vectorcardiogram (VCG). Initially, the electric connections used for recording the ECG were made to the limbs only. These connections to the right arm (RA), left arm (LA), left leg (LL) and right leg (RL) were introduced by Einthoven. The electrical variations detected by these leads are algebraically combined to form the bipolar leads I,II and III.
