Think about the heart’s orientation in the chest. The pointed tip of the heart—the apex—slants downward and to the left. It’s mainly formed by the left ventricle and sits around the left fifth intercostal space in the midclavicular line. The opposite end, the base, is higher up and oriented superiorly and posteriorly toward the right shoulder, and is formed by the atria and great vessels.
