1,758 Possible Causes for Abnormal ECG

  • Cardiac Arrhythmia

    RESULTS: Only five subjects showed signs of heart disease during the resting ECG; none of the exercise ECGs revealed any abnormalities, even after further cardiological examinations[ncbi.nlm.nih.gov] An ECG can show abnormal rhythms and stress on the heart.[dellchildrens.net] Because arrhythmia represents abrupt and abnormal ECG beats, physicians diagnose arrhythmia based on long-term ECG data using an ECG recording system like the Holter recorder[dx.doi.org]

  • Heart Failure

    A 65-year-old gentleman presented with an acute right middle cerebral artery territory infarction, and was found to have ECG abnormalities and left ventricular dysfunction[ncbi.nlm.nih.gov] An ECG may be done while you are resting or exercising. b. The ECG tracing may indicate that you have a heart abnormality.[ssa.gov] Additionally, when the cardiothoracic ratio is greater than 50%, 12-lead ECG and echocardiography should be performed.[ncbi.nlm.nih.gov]

  • Atrial Fibrillation

    At the same time, the harms of diagnostic follow-up and treatment prompted by abnormal ECG results are well established and include misdiagnosis and invasive testing.[ncbi.nlm.nih.gov] But the paper notes that abnormal ECGs were sent to a cardiologist for review, and also says that the Kardia produced some false positives (indications of AFib that the reviewing[spectrum.ieee.org] The performance of ECG itself is not associated with significant harm, although abnormal results may cause anxiety.[doi.org]

  • Duchenne Muscular Dystrophy

    The PR interval gradually increased with age, but no ECGs showed an abnormally prolonged PR interval.[ncbi.nlm.nih.gov] Decreased myocardial nNOS, increased iNOS and abnormal ECGs in mouse models of Duchenne muscular dystrophy. J Mol Cell Cardiol. 1999 ; 31 :1857–1862.[doi.org] Echocardiography and ECG are standardly used for screening and detection of cardiovascular abnormalities in these patients, although these tools are not always adequate to[ncbi.nlm.nih.gov]

  • Tachyarrhythmia

    However, an incidental discovery of an abnormal ECG without symptoms or family history may not necessarily imply syndrome phenotype.[bupacromwellhospital.com] The performance of ECG itself is not associated with significant harm, although abnormal results may cause anxiety.[doi.org] ECG changes, attributable to acute stroke vary widely in different series and occur in 15% to 30% of cases. [2] ECG abnormalities are more frequent with subarachnoid (SAH)[ruralneuropractice.com]

  • Idiopathic Ventricular Fibrillation

    Over a mean follow-up time of 85 47 months (median: 42 months), ECG was found abnormal in three cases.[ncbi.nlm.nih.gov] Serial studies after prolonged but successful resuscitation, including echocardiography, an electrocardiogram (ECG), and coronary angiography failed to reveal abnormal cardiac[ncbi.nlm.nih.gov] In the remaining eight patients (6 males; median age: 45 years), no ECG or structural abnormalities were detected during the follow-up.[ncbi.nlm.nih.gov]

  • Ventricular Fibrillation

    Over a mean follow-up time of 85 47 months (median: 42 months), ECG was found abnormal in three cases.[ncbi.nlm.nih.gov] Many kinds of abnormalities can often be seen on an ECG.[merckmanuals.com] Signal-averaged ECGs are abnormal in the majority of patients.[emedicine.medscape.com]

  • Becker Muscular Dystrophy

    One of them has an abnormal ECG that showed right ventricular hypertrophy and sinus tachycardia and the others have abnormal echocardiograms (ejection fraction ranging from[doi.org] Decreased myocardial nNOS, increased iNOS and abnormal ECGs in mouse models of Duchenne muscular dystrophy. J Mol Cell Cardiol. 1999 ; 31 :1857–1862.[doi.org] However, the shortcomings of a cardiac examination relying mainly on ECG findings are illustrated in this study: Only seven patients (46.7%) did demonstrate some ECG abnormalities[jcmr-online.biomedcentral.com]

  • Mucopolysaccharidosis

    Mucopolysaccharidosis type IVB (MPS IVB) is a very rare lysosomal storage disorder characterized by skeletal dysplasia, hearing disorder, and cardiac valvular disease. Herein, we report an extremely rare manifestation of MPS IVB in a 60-year-old female patient who underwent a successful aortic valve replacement. The[…][ncbi.nlm.nih.gov]

  • Chronic Thromboembolic Pulmonary Hypertension

    ECG signs of right heart strain include P-pulmonale, right bundle branch block, T-wave abnormalities in the chest leads and right-axis deviation [ 11 – 13 ].[err.ersjournals.com]
