翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク External counterpulsation ： ウィキペディア英語版 External counterpulsation External counterpulsation therapy (ECP) is a procedure performed on individuals with angina or heart failure or cardiomyopathy in order to diminish symptoms of ischemia, improve functional capacity and quality of life. In various studies, ECP has been shown to relieve angina, and decrease the degree of ischemia in a cardiac stress test.〔 ==Method== While an individual is undergoing ECP, he/she has pneumatic cuffs on his or her legs and is 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, ECP is similar to the intra-aortic balloon pump (IABP). Since it increases pressure in the aorta while the heart is relaxing (during diastole) ECP also increases blood flow into the coronary arteries, which also occurs during that phase. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「External counterpulsation」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
