In fact, asymptomatic ( or silent) ST- segment depression during ambulatory electrocardiogram monitoring occurs more often than symptomatic ST- segment depression in patients with coronary artery disease. Ischemia or ischaemia is a restriction in blood supply to tissues, causing a shortage of oxygen that is needed for cellular metabolism ( to keep tissue alive).
