A reliable method of determining the presence of a pericardial effusion has been evolved. Ultrasonic waves reflected from the posterior part of the anterior chest wall and from the anterior surface of the anterior myocardium and pericardium produce echoes separated from each other by a bare area. This bare area varies in width and the variation has the same periodicity as the cardiac cycle.

一种可靠的确定心包积液存在的方法已经形成。从前胸壁后部以及前心肌和心包前表面反射的超声波产生的回声被一个无回声区隔开。这个无回声区的宽度会变化，且这种变化与心动周期具有相同的周期性。
