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]
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.
Electrical alternans is an electrocardiographic phenomenon of alternation of QRS complex amplitude or axis between beats and a possible wandering base-line. It can be seen in cardiac tamponade and severe pericardial effusion and is thought to be related to changes in the ventricular electrical axis due to fluid in the pericardium, as the heart essentially wobbles in the fluid filled ...
It is clinically similar to a pericardial effusion, and, depending on the volume and rapidity with which it develops, may cause cardiac tamponade. [ 1 ] The condition can be caused by full-thickness necrosis (death) of the myocardium (heart muscle) after myocardial infarction , chest trauma , [ 2 ] and by over-prescription of anticoagulants .
By definition, a pericardial effusion occurs when the volume of fluid in the cavity exceeds the normal limit. [5] If large enough, it can compress the heart, causing cardiac tamponade and obstructive shock. [6] Some of the presenting symptoms are shortness of breath, chest pressure/pain, and malaise.
Beck's triad is a collection of three medical signs associated with acute cardiac tamponade, a medical emergency when excessive fluid accumulates in the pericardial sac around the heart and impairs its ability to pump blood. The signs are low arterial blood pressure, distended neck veins, and distant, muffled heart sounds. [1]
A very large hemorrhagic pericardial effusion due to malignancy as seen on ultrasound which was causing tamponade. closed arrow: the heart, open arrow: the effusion. Tamponade (/ ˌ t æ m. p ə ˈ n eɪ d / [1]) is the closure or blockage (as of a wound or body cavity) by or as if by a tampon, especially to stop bleeding. [2]
On auscultation, pericardial friction rub can be heard. Cardiac tamponade: Cardiac tamponade occurs due to fluid accumulation in the pericardial space and typically presents with chest pain often accompanied by symptoms like dyspnea, hypotension, and pulsus paradoxus. Clinical signs include Beck's triad—hypotension, jugular venous distension ...
