The function of the human heart relies on the complex interplay of preload, afterload, and contractility. Alterations of all three variables occur in disease states. New developments in monitoring allow assessment of cardiac function at the bedside and contribute to patient care.
人类心脏的功能依赖于前负荷、后负荷和收缩力之间复杂的相互作用。在疾病状态下，这三个变量都会发生改变。监测方面的新进展使得在床边就能评估心脏功能，并有助于患者护理。
