Estimates of peak systolic and diastolic rates of left ventricular wall movement were made in 23 patients by echocardiography and angiocardiography. Echocardiographic measurements were calculated as the rate of change of the transverse left ventricular dimension, derived continuously throughout the cardiac cycle. These were compared with similar plots of transverse left ventricular diameter, in the same patients, derived from digitized cineangiograms taken within 10 minutes of echocardiograms. The results indicate close correlation between the two methods, and suggest that either can be used to measure peak rates of left ventricular wall movements in patients with heart disease.
通过超声心动图和心血管造影术对23例患者左心室壁运动的收缩期和舒张期峰值速率进行了评估。超声心动图测量值计算为左心室横向维度的变化率,在整个心动周期中持续获取。将这些测量值与同一患者在超声心动图检查后10分钟内数字化电影血管造影获得的左心室横向直径的类似曲线进行比较。结果表明两种方法之间具有密切相关性,并提示在心脏病患者中,两种方法均可用于测量左心室壁运动的峰值速率。
