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]
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]
Purulent Pericarditis; Echocardiogram showing pericardial effusion with signs of cardiac tamponade: Specialty: Cardiology: Symptoms: substernal chest pain (exacerbated supine and with breathing deeply), dyspnea, fever, rigors/chills, and cardiorespiratory signs (i.e., tachycardia, friction rub, pulsus paradoxus, pericardial effusion, cardiac tamponade, pleural effusion)
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.
Symptoms usually improve in a few days to weeks but can occasionally last months. [3] Complications can include cardiac tamponade , myocarditis , and constrictive pericarditis . [ 1 ] [ 2 ] Pericarditis is an uncommon cause of chest pain. [ 9 ]
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. This is called cardiac tamponade. The chambers of the heart can collapse from this pressure. The right heart has thinner walls and collapses more easily.
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 differential diagnoses of Kussmaul's sign includes constrictive pericarditis, restrictive cardiomyopathy, pericardial effusion, and severe right-sided heart failure. [ citation needed ] With cardiac tamponade , jugular veins are distended and typically show a prominent x descent and an absent y descent as opposed to patients with ...
