Cardiac tamponade physiology describes a life-threatening condition where fluid accumulates in the pericardial sac, severely compressing the heart. This impedes the heart’s ability to fill with blood during diastole, leading to reduced cardiac output, hypotension, and potential circulatory collapse. Early diagnosis via medical ultrasound is crucial.
Ultrasound plays a vital role in identifying tamponade physiology, visualizing the fluid around the heart and assessing its hemodynamic impact. Key echocardiographic findings include right ventricular collapse, dilated inferior vena cava, and reciprocal respiratory variations in ventricular filling. Recognizing these signs promptly is essential for timely intervention and improved patient outcomes.
