当心脏的排出量不能满足机体代谢所需时,就会出现一系列临床现象,称为“心力衰竭”(简称“心衰”)。问题的关键并不在心排出量的绝对值是否降低,而在于供与求之间的严重失调。甲亢时,可因代谢需求超出心脏的供应能力,即使心排出量高于正常,亦可产 When the cardiac output can not meet the body’s metabolic needs, there will be a series of clinical phenomena, known as “heart failure” (referred to as “heart failure”). The crux of the matter does not concern whether the absolute value of emissions is reduced, but rather the serious imbalance between supply and demand. Hyperthyroidism, due to metabolic demand may exceed the supply capacity of the heart, even if the cardiac output higher than normal, but also produce
