以往对扩张型心肌病(DCM)的心脏功能注重于收缩性能的研究,晚近对其舒张性能的研究表明:左室舒张期最大压力下降速度(-dp/dt—max)和顺应性(△V/△P)降低同样可以导致左室舒末压(LVEDP)升高、充盈受阻、心搏出量减少。故仅评定收缩性能或舒张性能不能客观地反映DCM的左心功能。本文应用心电机械图
In the past, cardiac function of dilated cardiomyopathy (DCM) focused on the study of systolic performance. Recent studies on its diastolic performance showed that the maximal rate of decline in diastolic left ventricular pressure (-dp / dt-max) and compliance / △ P) reduction can also lead to elevated left ventricular end-diastolic pressure (LVEDP), filling obstruction, reduced cardiac output. Therefore, only the assessment of systolic or diastolic performance can not objectively reflect the DCM left ventricular function. This application of electrocardiogram mechanical map
