左心室射血分数 meaning in Chinese
left ventricular ejection fraction
lvef
Examples
- Secondary measures included exercise - induced ischemia and resting left entricular ejection fraction during follow - up
第二量度包括随访期间的运动诱发的局部缺血和静息性左心室射血分数。 - Additional , still can fire hematic score according to metrical left ventricle , will evaluate left ventricular and contractive function
另外，还可根据测量的左心室射血分数，来评价左心室收缩功能。 - This finding applied to patients irrespective of their left ventricular ejection fraction , a common measure of ventricular function
这一发现与患者的左心室射血分数? ?衡量左心室功能的一项参数? ?无关。 - Patients with above - median mpo levels in combination with above - median plasma amino - terminal pro - brain natriuretic peptide ( nt - probnp ) or below - median left ventricular ejection fraction ( lvef ) had significantly greater mortality compared with other patients
在mpo中位数以上水平伴血浆氨基末端前脑利钠肽中位数水平以上病人或左心室射血分数在中位数以下病人相对于其他病人有更高的死亡率。 - The predictive value of heart rate variability is independent of other noninvasive measures commonly used to predict prognosis of cardiac diseases , low left ventricular ejection fraction , and so on . like other risk predictors , measures of heart rate variability have modest positive predictive accuracy when used alone . however , combining measures of heart rate variability with other risk predictors yields a positive predictive accuracy of about 50 %
心率变异性的预测价值独立于其他非创伤性预测心脏疾病预后指标(降低的左心室射血分数，频发重复性室性心律失常等) ，在单独应用时阳性预报率较低，但与其他指标联合应用，阳性预报率可达50 。
