Lead MCL₁ views the lateral wall of the left ventricle.

Question

Quizplus · Accepted Answer

Lead MCL₁ is a variation of the chest lead V₁ and views the ventricular septum. The negative electrode is placed below the left clavicle toward the left shoulder, and the positive electrode is placed to the right of the sternum in the fourth intercostal space. In this lead the positive electrode is in a position to the right of the left ventricle. Because the primary wave of depolarization is directed toward the left ventricle, the QRS complex recorded in this lead will normally appear negative.
