ejection click

A cardiac sound in early systole, related to cardiac dilation or HTN in the great vessels–aorta and pulmonary artery; ECs may be so close to the first heart sound that they simulate a splitting thereof; aortic ECs are constant and best heard at the left lower sternal border, and occur with aortic dilation–aortic stenosis, Fallot's tetralogy, truncus arteriosus; pulmonary ECs occur with pulmonary stenosis, are best heard at the left midsternum and disappear with inspiration; a midsystolic EC heard at the apex preceding a late systolic murmur, suggests mitral valve prolapse
