The combination of these sensors and contact points yield the six classic frontal leads of a full 12-lead ECG: leads I, II, III, aVL, aVR, and aVF.

Elevated aVR was significantly associated with increased 30-day mortality among these patients, regardless of ST-segment changes in other ECG leads.

Again, reading off the computer screen the values of the amplitudes of ECG QRS complexes, it was calculated that the 8.9% increase in the patient's BW was associated with a 24%, 27.3%, 25.9%, 7.9% ...
