A standard exercise stress test employs an EKG (electrocardiogram) to watch closely any variation in the heart's electrical activity, the heart valves, the activities of the heart muscle, if the heart does not have shortage of blood flow during exercise and to study how heart functions when undergoing physical activity.

Diastole and systole are two levels of the cardiac cycle. They are seen during heart beats function as it pumps blood using a collection of blood vessels that transports blood to each and every singular part of the body. Systole is produced during contraction of the heart to pump blood out, and diastole is produced during relaxation of the heart when it contracts.

Let's consider, 120/80 mm Hg. The up figure stands for the level of pressure in the arteries when the heart muscle contracts --- systolic pressure. The below figure stands for blood pressure as seen when the heart muscle is between beats--- diastolic pressure.
