两维超声心动图(2DE)可以准确测定左室喷血分数(LVEF),然而较少用于测定左室舒张功能。45例窦性心律的受检者在心导管检查前1小时内接受2DE检查,测定左室前半期充盈分数(1/2FF)。11例左室造影图象不佳或频发室性早搏,3例2DE图象不佳,4例心率<110 bpm,均予剔除。其余27(男21、女6)例,平均年龄53(29～72)岁,分析如下。其中5例冠状动脉造影和室壁活动未见异常,其LVEF≥0.50。另18例至少1支冠状动脉主支(内径)狭窄≥50％:其中8例室壁活动和LVEF正
Two-dimensional echocardiography (2DE) can accurately measure left ventricular ejection fraction (LVEF), but less used to measure left ventricular diastolic function. Forty-five patients with sinus rhythm underwent 2DE within 1 hour prior to cardiac catheterization, and their left ventricular filling fraction (1 / 2FF) was measured. Eleven patients had poor left ventricular imaging or frequent premature ventricular contractions, 3 patients had poor 2DE images, and 4 patients with heart rate <110 bpm were excluded. The remaining 27 (male 21, female 6) cases, the average age of 53 (29 ~ 72) years old, the analysis is as follows. Among them, 5 cases had abnormal coronary angiography and wall activity, and LVEF≥0.50. The other 18 cases of at least 1 coronary artery (diameter) stenosis ≥ 50%: 8 cases of wall activity and LVEF positive
