The general and local ejection fractions (EF) of the left ventricle were studied in 112 patients with grade I hypertensive disease and in 20 practically healthy persons at rest and during static isometric loads. At rest general and local EF were diverse. During loads both reduction and increase of general EF were observed. Increase of general and local EF is a result of adequate physiological reaction of the myocardium while their reduction indicates limitation of the myocardial reserve of the left ventricle.
对112例I级高血压病患者和20名实际健康者在静息状态及静态等长负荷期间的左心室总体和局部射血分数（EF）进行了研究。静息时，总体和局部EF各不相同。负荷期间，观察到总体EF既有降低也有升高。总体和局部EF升高是心肌充分生理反应的结果，而其降低则表明左心室心肌储备受限。
