12 Possible Causes for Diminished Heart Sounds, Low-Voltage Electrocardiogram, Pericardial Knock

  • Chronic Constrictive Pericarditis

    Negative predictors of survival were found to be preoperative NYHA class IV (P 0.01), low-voltage electrocardiogram (ECG) (P 0.01), ascites (P 0.01), dyspnea at rest (P 0.05[ncbi.nlm.nih.gov] 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] 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

    Initial workup will include an electrocardiogram which may show: Low voltage Electric alterans A chest X-ray may show an enlarged globular heart.[symptoma.com] 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] 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]

  • Cardiac Tamponade

    The electrocardiogram showed low-voltage QRS complex with electrical alternans.[ncbi.nlm.nih.gov] , and diminished heart sounds) Cold, clammy extremities Anxiety, restlessness Diagnosis Blood tests EKG, Chest X-ray Cardiac ECHO Treatment Oxygen IV fluids Medications to[cardiachealth.org] knock Tension pneumothorax distinguishing factors decreased or absent breath sounds hyperresonant percussion Treatment Management approach all approaches focus on removal[medbullets.com]

  • Malignant Pericardial Effusion

    Prominent low voltage QRS complexes in all derivations were obtained on electrocardiogram (Figure 1).[ispub.com] knock (60–200 msec after the second heart sound), which is caused by sudden termination of ventricular inflow by the encasing pericardium.[clevelandclinicmeded.com] Due to cardiac relaxation limitations, the patient presents congested jugular veins, tachycardia, arrhythmia, and low voltage criteria on electrocardiograms ( 1, 3, 7 ).[ispub.com]

  • Pericardial Calcification

    A low voltage electrocardiogram (ECG) and increased wall thickness with abnormal texture on echocardiography are the classic findings.[acc.org] 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] Physical examination revealed increased jugular venous pressure (14 cm of water), ascites along with presence of Kussmaul sign and pericardial knock.[jacpjournal.org]

  • Constrictive Pericarditis

    Low voltage is not commonly present.[clinicaladvisor.com] 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] Pericardial Knock (Constrictive Pericarditis) The early diastolic sound of pericardial constriction occurs slightly earlier than the average third heart sound.[podbay.fm]

  • Radiation Pericarditis

    ELECTROCARDIOGRAM (see Table 10 ) may show low voltage and electrical alternans.[brown.edu] 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] This includes a pericardial knock Pericardial rub (heard best while leaning forwards) and distant heart sounds Abdomen Hepatomegaly Ascites Extremities Ankle edema Electrocardiogram[wikidoc.org]

  • Pericardial Disorder

    A, Before pericardiocentesis, the complexes are low voltage (R wave 1 mV) and heart rate is 140 beats per minute (bpm).[veteriankey.com] 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] Kussmaul sign and pericardial knock are other typical physical findings.[thoracickey.com]

  • Pericarditis

    QRS voltage 25 0.5 mV in limb and less 1 mV in precordial derivations. 26 In our case, the electrocardiogram revealed low voltage with tachycardia, inferolateral T wave inversion[scielo.org.mx] […] dullness, diminished or absent apical impulse, and distant heart sounds.[healthcentral.com] knock. [11] Treatment [ edit ] The definitive treatment for constrictive pericarditis is pericardial stripping, which is a surgical procedure where the entire pericardium[en.wikipedia.org]

  • Ascites

    The electrocardiogram is not characteristic and may reveal nonspecific repolarization changes and low-voltage electrical activity.[scielo.isciii.es] Examination showed elevated jugular venous pressure with two prominent descents, high pitched diastolic heart sound (pericardial knock).[ncbi.nlm.nih.gov] Heart auscultation was normal. Lung auscultation detected diminished breath sounds at the lower right lung.[scielo.isciii.es]
