近年来对ECG左室肥大的表现区分两种负荷过重的理论一直有争议。本文收集临床无明显心衰而ECG表现左室肥大伴收缩期负荷过重21例,伴舒张期负荷过重13例,用UCG测量左室腔径、室壁厚度、左室舒末容量、RWT、射血分数、EF斜率等十一项指标,对ECG表现的两种负荷过重作了对比研究。统计学分析表明:前者心脏以左室壁增厚为特点,后者以左室腔扩大为特点,可以根据ECG左室负荷过重的属型推测血流动力学改变及心脏病理改变,为病因诊断提供线索。
In recent years, the distinction between two manifestations of LV hypertrophy has been controversial. This collection of clinical no significant heart failure and ECG performance of left ventricular hypertrophy with systolic overload in 21 cases, with diastolic overloaded in 13 cases, with UCG measurement of left ventricular cavity diameter, wall thickness, left ventricular end-diastolic volume, RWT , Ejection fraction, EF slope and other eleven indicators, ECG performance of the two overload compared. Statistical analysis showed that: the former heart to the left ventricular wall thickening is characterized by the latter to expand the left ventricular cavity is characterized by the left ventricular overload can be genotyped to speculate hemodynamic changes and cardiac pathology, the etiology Diagnosis provides clues.
