A depression on both sides of the chest wall of a child between the pectoral muscles and the lower margin of the ribcage. It is caused by exaggerated suction of the diaphragm when breathing in and develops in conditions in which the airways are partially obstructed or when the lungs are abnormally congested due to some congenital abnormality of the heart.
Harrison’s sulcus is a visible indentation observed at the lower part of a child’s ribcage. It typically occurs due to excessive suction of the diaphragm muscle during respiratory conditions like severe asthma. Additionally, this depression can result from the normal pull of the diaphragm on weakened ribs, which may be seen in conditions such as rickets.
