充血性心力衰竭(CHF)是临床常见而又不能下简单定义的综合症.传统习惯依其呼吸短促、疲劳,及劳力耐受程度作为对病情的判断,往往造成主观片面、不可靠。按纽约心脏病协会的心功能分级亦难以反映患者确切的心功能和泵储备力。静息状态下所测定心脏射血分数、心输出量、左心充盈压与劳力耐受性缺乏相关性。不少学者探索活动平板运动试验非侵入性测定有氧代谢能力和无氧代谢阈 Congestive heart failure (CHF) is a common and can not be a simple clinical syndrome defined by the traditional habits of its shortness of breath, fatigue, and labor tolerance as a judgment of the disease, often resulting in subjective one-sided, unreliable. According to the New York Heart Association cardiac function classification is also difficult to reflect the exact patient’s heart function and pump reserve. Cardiac ejection fraction, cardiac output, and left ventricular filling pressure measured at rest were not correlated with labor tolerance. Many scholars explore the activities of non-invasive testing of treadmill exercise aerobic metabolism and anaerobic metabolism threshold
