A further decrease of cardiac input and output is typical in phase III of the progression of cardiac tamponade. This is caused by the equilibration of left ventricular filling and pericardial pressure, leading to “severe deterioration of end-organ perfusion.” [ 11 ] Some of the symptoms, as a consequence, include abdominal pain due to liver ...
Echocardiogram of cardiac tamponade. Fluid surrounding the heart impairs proper filling. This swinging of the heart causes electrical alternans seen on EKG. A pericardial effusion is fluid in the pericardial sac. When large enough, the pressure compresses the heart. This causes shock by preventing the heart from filling with blood.
These three findings together should raise suspicion for impending hemodynamic instability associated with cardiac tamponade. [citation needed] Echocardiogram (ultrasound): when pericardial effusion is suspected, echocardiography usually confirms the diagnosis and allows assessment of the size, location and signs of hemodynamic instability.

Focused assessment with sonography in trauma (commonly abbreviated as FAST) is a rapid bedside ultrasound examination performed by surgeons, emergency physicians, and paramedics as a screening test for blood around the heart (pericardial effusion) or abdominal organs (hemoperitoneum) after trauma.
Pericardiocentesis can be used to diagnose and treat cardiac tamponade. [3] [4] Cardiac tamponade is a medical emergency in which excessive accumulation of fluid within the pericardium (pericardial effusion) creates increased pressure. [5] This prevents the heart from filling normally with blood.
Cardiac tamponade is accumulation of enough fluid in the pericardial space --- pericardial effusion--- to cause serious obstruction to the inflow of blood to the heart. Signs of cardiac tamponade include distended neck veins, muffled heart sounds when listening with a stethoscope , and low blood pressure (together known as Beck's triad ). [ 2 ]

The diagnosis of tamponade can be confirmed with trans-thoracic echocardiography (TTE), which should show a large pericardial effusion and diastolic collapse of the right ventricle and right atrium. Chest X-ray usually shows an enlarged cardiac silhouette ("water bottle" appearance) and clear lungs. Pulmonary congestion is typically not seen ...
