  2. Cardiac tamponade - Wikipedia

    en.wikipedia.org/wiki/Cardiac_tamponade

    Tamponade can often be diagnosed radiographically. Echocardiography, which is the diagnostic test of choice, often demonstrates an enlarged pericardium or collapsed ventricles. A large cardiac tamponade will show as an enlarged globular-shaped heart on chest x-ray.

  3. Beck's triad (cardiology) - Wikipedia

    en.wikipedia.org/wiki/Beck's_triad_(cardiology)

    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]

  4. Pericardial effusion - Wikipedia

    en.wikipedia.org/wiki/Pericardial_effusion

    A pericardial effusion with enough pressure to adversely affect heart function is called cardiac tamponade. [1] Pericardial effusions can cause cardiac tamponade in acute settings with fluid as little as 150mL. In chronic settings, however, fluid can accumulate anywhere up to 2L before an effusion causes cardiac tamponade.

  5. Electrical alternans - Wikipedia

    en.wikipedia.org/wiki/Electrical_alternans

    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 ...

  6. Purulent pericarditis - Wikipedia

    en.wikipedia.org/wiki/Purulent_pericarditis

    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)

  7. Acute pericarditis - Wikipedia

    en.wikipedia.org/wiki/Acute_pericarditis

    Pericardiocentesis is a procedure whereby the fluid in a pericardial effusion is removed through a needle. It is performed under the following conditions: [15] presence of moderate or severe cardiac tamponade; diagnostic purpose for suspected purulent, tuberculosis, or neoplastic pericarditis; persistent symptomatic pericardial effusion

  8. Kussmaul's sign - Wikipedia

    en.wikipedia.org/wiki/Kussmaul's_sign

    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 ...

  9. Pericardiocentesis - Wikipedia

    en.wikipedia.org/wiki/Pericardiocentesis

    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.
