EECP

EECP Therapy is an outpatient treatment for angina and heart failure. Treatments are usually given for an hour each day, five days a week, for a total of 35 hours.

While an individual is undergoing EECP, one has pneumatic cuffs on his or her legs and are connected to telemetry monitors that monitor heart rate and rhythm. The most common type in use involves three cuffs placed on each leg (on the calves, the lower thighs, and the upper thighs (or buttock)).

The cuffs are timed to inflate and deflate based on the individual's electrocardiogram. The cuffs should ideally inflate at the beginning of diastole and deflate at the beginning of systole. During the inflation portion of the cycle, the calf cuffs inflate first, then the lower thigh cuffs and finally the upper thigh cuffs. Inflation is controlled by a pressure monitor, and the cuffs are inflated to about 200 mmHg.

When timed correctly, this will decrease the afterload that the heart has to pump against, and increase the preload that fills the heart, increasing the cardiac output. In this way, EECP is similar to the intra-aortic balloon pump (IABP). Since it increases pressure in the aorta while the heart is relaxing (during diastole) EECP also increases blood flow into the coronary arteries, which also occurs during that phase.
