冠状动脉旁路手术病人,用定轴法(fixed-axisanalysis system)分析术前、术后超声心动图时,常出现术后室间隔活动减低、左室侧壁活动增强现象,以致难以正确评价术后局部室壁活动异常的意义。作者1983年曾著文阐明此乃心脏手术后,收缩期心脏向前内侧移位所致,并应用浮轴法(floating-axisanalysis system)纠正定轴法中室间隔和侧壁活动异常的假象。本文探讨冠状动脉旁路术并发围术期心肌梗塞病人中浮轴法是否同样可纠正定轴法所致室间隔和侧壁活动异常的假象。方法:三组受检者分别用定轴法和浮轴法分析
Coronary artery bypass surgery patients using the fixed-axis axis analysis (fixed-axisanalysis system) analysis of preoperative and postoperative echocardiography, often postoperative ventricular septal activity decreased, left ventricular wall activity increased phenomenon, it is difficult to correctly evaluate the operation After the local wall activity abnormalities significance. The author has written in 1983 that this is after cardiac surgery, systolic heart displacement caused by the forward medial, and the use of floating-axis method (floating-axisanalysis system) to correct the fixed-axis method of ventricular septal and lateral abnormalities of the illusion. This article discusses the coronary artery bypass surgery complicated with perioperative myocardial infarction in patients with floating axis method can also correct the shaft method induced ventricular septal and lateral abnormalities of the illusion. Methods: The three groups of subjects were respectively analyzed by the fixed axis method and the floating axis method
