心包填塞的經典表現為貝克三徵象(Beck's Triad):心音模糊、頸靜脈怒張、低血壓。此外,脈搏奇脈(Pulsus paradoxus,吸氣時收縮壓下降超過 10mmHg)也是極具診斷價值的臨床指標,與心包膜內壓上升限制心室填充有關。
Cardiac tamponade is characterized by Beck's triad: muffled heart sounds, jugular vein distension, and hypotension due to decreased cardiac output. Additionally, pulsus paradoxus, defined as a drop in systolic blood pressure greater than 10 mmHg during inspiration, is a classic diagnostic sign. Tachycardia, rather than bradycardia, is typically observed as the heart attempts to compensate for reduced stroke volume.
