Cardiac tamponade results from pericardial fluid accumulating under pressure, impairing cardiac filling and reducing stroke volume. The pathophysiology, clinical presentation, diagnosis, and treatment of cardiac tamponade will be reviewed here.

2023年8月7日 · Cardiac tamponade is a medical emergency that takes place when abnormal amounts of fluid accumulate in the pericardial sac compressing the heart and leading to a decrease in cardiac output and shock.

2024年3月5日 · Low-pressure tamponade is essentially a shock state due to a combination of hypovolemia and elevated pericardial pressure. The crux of cardiac failure in tamponade is a reduction in cardiac filling due to a decrease in the pressure gradient between the central venous

Cardiac tamponade, also known as pericardial tamponade (/ ˌ t æ m. p ə ˈ n eɪ d / [4]), is a compression of the heart due to pericardial effusion (the build-up of pericardial fluid in the sac around the heart). [2] Onset may be rapid or gradual. [2]

2023年7月31日 · Cardiac tamponade is a grave condition that happens after sudden and/or excessive accumulation of fluid in the pericardial space. The state restricts the appropriate filling of the cardiac chambers, disturbing normal hemodynamics and ultimately causing hypotension and cardiac arrest.

2023年4月28日 · Cardiac tamponade — or pericardial tamponade — happens when the pericardium fills with fluid (usually pericardial fluid or blood). Because the fluid has nowhere to go, your heart runs out of room and can’t expand enough to fill effectively.

Cardiac tamponade is defined as significant compression of the heart by accumulating pericardial contents, including effusion fluids, blood, clots, pus, and gas, singly or in combinations. “Significant compression” depends on whether tamponade is approached from a purely physiologic or clinical standpoint.

Cardiac tamponade is a life-threatening, slow or rapid compression of the heart due to the pericardial accumulation of fluid, pus, blood, clots or gas as a result of inflammation, trauma, rupture of the heart or aortic dissection. Onset to (acute, subacute) or (chronic if more than three months). 10-50 ml of pericardial fluid is normally present.

Cardiac Tamponade Physiology. Cardiac tamponade is a life-threatening condition caused by accumulation of fluid in the pericardial space that compresses the cardiac chambers and restricts them from normal filling (9, 23, 24). The rate of fluid accumulation will …

2016年7月13日 · Interaction of respiratory variation in right atrial venous return with this decreased diastolic filling gives rise to all the interesting clinical and echocardiographic signs of cardiac tamponade. Beck's Triad: Muffled heart sounds, hypotension and raised CVP.
