Abstract

Forty-nine normal children underwent echocardiography to study the role of automatic border detection (ABD) in diastolic evaluation by (1) determining the relationship of diastolic ABD indexes to heart rate and traditional diastolic indexes and (2) establishing inter-observer variability. ABD diastolic indexes were less associated with heart rate than were M-mode and Doppler diastolic indexes. ABD left ventricular peak filling rate correlated with Doppler mitral E wave peak velocity. Interobserver variability for ABD indexes ranged from 4% to 24%. We then compared the ability of ABD left ventricular filling rate to M-mode and Doppler indexes to detect diastolic dysfunction in a test group of 20 children with diastolic disease. ABD left ventricular peak filling rate had the highest sensitivity of all indexes (90%). Thus ABD left ventricular peak filling rate is an accurate index of diastolic function that is readily usable by almost all clinical laboratories.

摘要

49名正常儿童接受了超声心动图检查，以研究自动边界检测（ABD）在舒张功能评估中的作用，具体包括：（1）确定舒张期ABD指标与心率及传统舒张期指标之间的关系；（2）确定观察者间的变异性。与M型和多普勒舒张期指标相比，ABD舒张期指标与心率的相关性较小。ABD左心室峰值充盈率与多普勒二尖瓣E波峰值速度相关。ABD指标的观察者间变异性在4%至24%之间。然后，我们在一个由20名患有舒张期疾病的儿童组成的测试组中，比较了ABD左心室充盈率与M型和多普勒指标检测舒张功能障碍的能力。ABD左心室峰值充盈率在所有指标中具有最高的敏感性（90%）。因此，ABD左心室峰值充盈率是舒张功能的一个准确指标，几乎所有临床实验室都可轻松使用。
