Q: Enhanced external counterpulsation (EECP) is performed during which cycle of the heart? (Select one)

A) Diastole
B) systole


EECP relies on the concept of diastolic augmentation i.e. retrograde aortic blood flow during the diastole. It is done by applying cuffs, wrapped around the patient’s legs and providing sequential pressure at about 300 mm Hg from calf  to the lower and upper thighs. It may be used as an adjuvant or  salvage or rescue therapy in angina or congestive heart failure.
