18 Possible Causes for Cardiac Output Decreased, Diminished Heart Sounds, Pericardial Knock

  • Chronic Constrictive Pericarditis

    Signs may include hypotension, elevated jugular venous pressure (JVP) and diminished heart sounds (Beck's triad or acute compression triad described in 1935 with cardiac tamponade[patient.info] CARDIAC CATHETERIZATION  CVP greater than 14 mm hg  Near equalization of CVP, PA diastolic pressure, and capillary wedge pressures.  Decreased cardiac output.  “square[slideshare.net] The beginning of this anomalous movement was coincident with the pericardial knock in the phonocardiogram and its peak was coincident with the simultaneously recorded deep[ncbi.nlm.nih.gov]

  • Pericardial Effusion

    On physical examination classical signs include neck vein distention with elevated jugular venous pressure at bedside examination, pulsus paradoxus, and diminished heart sounds[eurheartj.oxfordjournals.org] Evaluation As fluid accumulates in the pericardium, the increase in intrapericardial pressure affects diastolic filling of the heart, leading to decreased cardiac output.[oncologypro.esmo.org] See also constrictive pericarditis. pericardial friction rub see pericardial rub. pericardial knock an early diastolic sound caused by loss of pericardial elasticity accompanying[medical-dictionary.thefreedictionary.com]

  • Acute Pericarditis

    Further fluid accumulation beyond this amount however can result in marked increases in pericardial pressure, causing decreased cardiac output and hypotension.[ceufast.com] Accordingly, patients present with fatigue, jugular vein distention, peripheral edema, and a characteristic pericardial knock on auscultation, caused by a sudden stop in ventricular[amboss.com] ., compromises the heart’s ability to pump blood, leading to decreased cardiac output and stroke volume).[uspharmacist.com]

  • Malignant Pericardial Effusion

    Evaluation As fluid accumulates in the pericardium, the increase in intrapericardial pressure affects diastolic filling of the heart, leading to decreased cardiac output.[oncologypro.esmo.org] knock (60–200 msec after the second heart sound), which is caused by sudden termination of ventricular inflow by the encasing pericardium.[clevelandclinicmeded.com] Predictors of post pericardiotomy low cardiac output syndrome in patients with pericardial effusion.[jbiomed.com]

  • Pericardial Calcification

    Signs may include hypotension, elevated jugular venous pressure (JVP) and diminished heart sounds (Beck's triad or acute compression triad described in 1935 with cardiac tamponade[patient.info] LOW CARDIAC OUTPUT • DYSPNEA • FATIGUE • TACHYCARDIA 3.[brown.edu] Physical examination revealed increased jugular venous pressure (14 cm of water), ascites along with presence of Kussmaul sign and pericardial knock.[jacpjournal.org]
