of heart muscle. More specifically, an area of heart muscle has undergone coagulative necrosis (re?) due to sudden, prolonged ischemia. If the zone of necrosis (death) is limited only to the innermost portion of the wall of the left ventricle (i.e. right next to the inner lining of the heart), then this is a …

HEART
Reduced blood flow in coronary arteries causes ANGINA PECTORIS (chest pain). The myocardium is suffering from ISCHEMIA (reduction in blood flow that leads to HYPOXIA-low oxygenation) Medicinally treated with nitroglycerine. It dilates coronary arteries. HEART MURMURS: Caused by a problem with a valve. Due to stenosis (narrowing of the space).
NORMAL ECG
