Abstract
Fourteen patients with pericardial effusions without clinical signs of tamponade (pulsus paradoxus or other cardiac and circulatory abnormalities) showed inspiratory reductions in echocardiographic left ventricular internal diastolic diameter which correlated directly with the exaggerated respiratory changes in systolic time intervals (both pre-ejection period and left ventricular ejection time). Excessive pericardial fluid affects left ventricular function even in the absence of clinical manifestations.
摘要
14例有心包积液但无心脏压塞临床体征（奇脉或其他心脏及循环系统异常）的患者，超声心动图显示吸气时左心室内径舒张期减小，这与收缩期时间间期（射血前期和左心室射血时间）的过度呼吸变化直接相关。即使没有临床表现，过多的心包积液也会影响左心室功能。
