ICG舒张晚期波形指数在心功能检测中的应用

Use of ICG late diastolic wave index in determination of cardiac funtion

采用ＩＣＧ中的ｈＡ（ｄｚ／ｄｔ）ｍａｘ作为心房收缩力的观察指标，ｈｃ（ｄｚ／ｄｔ）ｍａｘ作为心室收缩力的观察指标，把Ａ／Ｃ（ｄｚ／ｄｔ）ｍａｘ作为心室舒张晚期波形指数，对高血压性心脏病（高心病）、冠状动脉粥样硬化性心脏病（冠心病）和肺源性心脏病（肺心病）共８１例的Ａ／Ｃ（ｄｚ／ｄｔ）ｍａｘ进行了检测，并与健康组５６例进行对照研究。结果提示：３组心脏病的舒张晚期功能均呈现出明显减退。因此，Ａ／Ｃ（ｄｚ／ｄｔ）ｍａｘ对心室功能不全的检测可视为一项敏感的无创性检查方法。

In order to study the regular pattern of the changes of ventricular function in late diastolic phase,hA (dz/dt)max and hc (dz/dt)max in ICG served as observation indexes of contractibility of auricles and ventricles respectively and A/C (dz/dt) max was used asventricular late diastolic wave index. The above indexes were determined in 81 patients with hypertensive heart disease, coronary heart disease and cor pumonale. The results were compared with those in 56 healthy persons and showed that the late diastolic cardiac function in all the three groups of patients deteriorated. It fol lows that A/C(dz/dt) max can be regarded as a sensitive noninvasive means for determination of cardiac ventricular dys function.
