Percussion of the anterior chest wall reveals an area of dullness over the centre and left of the sternum. This is the area of superficial cardiac dullness. It is roughly triangular in shape and corresponds to the part of the sternocostal surface of the heart that is both close to the anterior chest wall and not covered by lung.
