Myocardial ischemia occurs when the supply of oxygen and nutrients to the heart, or a portion thereof, is inadequate to meet the metabolic demands of the heart.
Ischemia can occur as a result of narrowing of the arteries, or with complete block of an artery.
To understand the mechanistic basis for changes that take place in the electrical activity of cells under normal conditions, and when they are deprived of oxygen and nutrients. To understand how these changes impact on activation of the heart. To understand how these changes influence the electrocardiogram.
