Lead I: Positive electrode is placed just the left clavicle Negative electrode place just below the right clavicle Provides information the left lateral wall of chest. Lead II: Positive electrode just below the left pectoral muscle Negative electrode just below the right clavicle Provides information about the inferior wall of the heart Very common in cardiac monitoring because position of this lead is to actual conduction pathways. Lead III: Positive electrode is at the left pectoral muscle, and negative is the left clavicle. Provides information about the inferior wall of the heart MCL I Negative electrode is below the left clavicle and positive is at the right of the sternum at the fourth intercostals space. Useful in assessing the anterior wall of the heart (LV) and the conduction through the ventricles.
