Average x, y and z components of positioning errors for precordial electrodes. Averages (bars) and Standard Deviations (segments) of the errors (distance from the expected location reported in centimeters for each of the x, y and z axes of the space) in the placement of the precordial electrodes on the mannequin (a) and on the patient’s chest (b) by the ten untrained users. V1, V2, V3, V4, V5 and V6 are the six precordial locations;
