37 Possible Causes for Left Atrial Enlargement, Low-Voltage Electrocardiogram

  • Cardiomyopathy

    Common ECG associations with DCM Left atrial enlargement - may progress to atrial fibrillation.[lifeinthefastlane.com] […] ventricular wall thickness Associated abnormalities of the mitral valve and left ventricular outflow tract Assessment of latent obstruction Left atrial enlargement Assessment[escardio.org] Findings may be summarized as follows: Abnormal systolic anterior leaflet motion of the mitral valve Left ventricular hypertrophy (LVH) Left atrial enlargement Small ventricular[emedicine.com]

  • Chronic Constrictive Pericarditis

    A possible mechanism for left atrial enlargement has been discussed. Refbacks There are currently no refbacks.[pkheartjournal.com] 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] The electrocardiogram (Fig. 2) revealed a diphasic T,; T, was inverted. QRS, was of low voltage, and S, was prominent.[kundoc.com]

  • Angina Pectoris

    Echocardiography showed normal left ventricular function, mild left ventricular hypertrophy, moderate left atrial enlargement with mild mitral insufficiency, and moderate[ncbi.nlm.nih.gov] The electrocardiogram showed normal sinus rhythm, incomplete right bundle branch block with normal axis, and borderline left atrial abnormality.[ncbi.nlm.nih.gov]

  • Pericardial Effusion

    atrial enlargement may be an indirect clue 2 a differential density sign at cardiac borders has been suggested 9 , but its specificity is limited usually requires greater[radiopaedia.org] 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] atrial enlargement may be an indirect clue 2 a differential density sign at cardiac borders has been suggested 9, but its specificity is limited serially enlarging cardiothoracic[radiopaedia.org]

  • Systemic Amyloidosis

    Severely reduced atrial contractility secondary to amyloid infiltrate, increased left atrial afterload and left atrial enlargement with depressed LV systolic and diastolic[bjcardio.co.uk] In all cases, electrocardiogram showed low voltage in the limb leads and a pseudoinfarct pattern in the chest leads, and echocardiography showed left ventricular wall thickening[ncbi.nlm.nih.gov] The patient's history of pulmonary hypertension and low-voltage QRS complex on electrocardiogram were consistent with cardiac amyloid infiltration and resultant restrictive[cutis.com]

  • Restrictive Cardiomyopathy

    A low voltage electrocardiogram (ECG) and increased wall thickness with abnormal texture on echocardiography are the classic findings.[acc.org] Afterwards, another 24 year old sib had a syncope with head trauma: ECG showed right atrial enlargement, left bundle branch block.[ncbi.nlm.nih.gov] We present a 62-year-old with a history of heart failure, which in its assessment highlights the discrepancy between the low voltage ventricular complexes in the electrocardiogram[ncbi.nlm.nih.gov]

  • Cardiac Amyloidosis

    Electrocardiogram depicted low voltage in limb leads and a prolonged PR interval.[ncbi.nlm.nih.gov] […] reversal (AR) 35 cm/s duration of AR exceeds mitral A wave by 20 ms biatrial enlargement right atrial enlargement left atrial enlargement atrial strain: can be significantly[radiopaedia.org] The electrocardiogram showed sinus tachycardia and low voltage criteria.[ncbi.nlm.nih.gov]

  • Ischemic Cardiomyopathy

    It stabilizes sinus rhythm in patients with heart failure and atrial fibrillation even with enlarged left atria.[symptoma.com]

  • Cardiac Tamponade

    […] and right atrial pressures are equal Chest X-ray : To look for an enlarged heart Physical exam, including listening with a stethoscope for distant heart sounds and dullness[utswmedicine.org] The electrocardiogram showed low-voltage QRS complex with electrical alternans.[ncbi.nlm.nih.gov] , which may also show low voltage QRS complexes, as well as general signs and symptoms of shock (such as fast heart rate, shortness of breath and decreasing level of consciousness[en.wikipedia.org]

  • Amyloidosis

    low-voltage amplitudes.[doi.org] […] and regurgitation, atrial enlargement, and pericardial effusion.[circ.ahajournals.org] (for example: low voltage).[rarediseases.org]
