What causes heaving apex beat?

This is usually due to a thick chest wall, emphysema, pericardial infusion, shock or dextrocardia. Rolling the patient into the left lateral position may enable the apex beat to be palpated (Scott and MacInnes, 2006). The location and the character of the apex beat should be noted.

Is a palpable apex beat normal?

The normal apex beat can be palpated in the precordium left 5th intercostal space, half-inch medial to the left midclavicular line and 3–4 inches left of left border of sternum. In children the apex beat occurs in the fourth rib interspace medial to the nipple.
