55 Possible Causes for Inverted P Wave, Right Axis Deviation

  • Spontaneous Pneumothorax

    An ECG was administered; findings indicated reversal of the arm leads (right axis deviation and inverted P waves in lead I), but there was no actual limb lead reversal present[ncbi.nlm.nih.gov] These findings include axis deviation, T-wave inversion, and right bundle branch block.[ncbi.nlm.nih.gov] When an ECG has the arm leads incorrectly placed, the ECG will display right axis deviation and inversion of the P waves in lead I.[ncbi.nlm.nih.gov]

  • Patent Foramen Ovale

    deviation of the QRS complex while those with a secundum ASD have a right axis deviation of the QRS complex.[marmur.com] […] can cause an increased distance of internodal conduction from the SA node to the AV node. 5 In addition to the PR prolongation, individuals with a primum ASD have a left axis[marmur.com]

  • Dextrocardia

    , aka ‘global negativity’ (inverted P wave, negative QRS, inverted T wave) Absent R-wave progression in the chest leads (dominant S waves throughout) These changes can be[litfl.com] axis deviation.[web.archive.org] […] by, last update April 30, 2019 ECG Features of Dextrocardia Right axis deviation Positive QRS complexes (with upright P and T waves) in aVR Lead I: inversion of all complexes[lifeinthefastlane.com]

  • Cardiomyopathy

    There are some signs of left atrial enlargement — leftward deviation of the P wave axis (positive P waves in I and aVL, inverted in III and aVF) and prolongation of the terminal[lifeinthefastlane.com] Electrocardiogram showed right axis deviation, poor R-wave progression, and diffuse ST-segment elevation in the anterior leads, and cardiomegaly was observed by roentgenogram[ncbi.nlm.nih.gov] deviation (right or left) Conduction abnormalities (P-R prolongation, bundle-branch block) Sinus bradycardia with ectopic atrial rhythm Atrial enlargement Abnormal and prominent[emedicine.medscape.com]

  • Ostium Primum Atrial Septal Defect

    Mild right ventricular hypertrophy Inverted P waves in Sinous Venosus type Right Bundle Branch Block is seen which is partial or complete 17.[slideshare.net] In primum defects left axis deviation is seen in most patients with an axis of -30 degrees and very few patients have right axis deviation.[en.wikipedia.org] In Primum defects left axis deviation is seen in most patients with an axis of -30 degrees and very few patients have right axis deviation.[ipfs.io]

  • Right Ventricular Hypertrophy

    T waves in right praecordial leads - V2, V3 - will be present in severe cases; it is normal to have inverted T waves in V1 peaked P waves may also occur due to right atrial[gpnotebook.co.uk] Example 4 Right ventricular hypertrophy in a patient with arrhythmogenic right ventricular cardiomyopathy (ARVC): Right axis deviation.[lifeinthefastlane.com] […] congenitale S1 S2 S3 pattern in children Tall R wave in V1 or qR in V1 R wave greater than S wave in V1 R wave progression reversal Inverted T wave in the anterior precordial[wikidoc.org]

  • Cor Pulmonale

    The most typical ECG findings in emphysema are: Rightward shift of the P wave axis with prominent P waves in the inferior leads and flattened or inverted P waves in leads[lifeinthefastlane.com] Right axis deviation and low voltage may be noted in patients with pulmonary emphysema.[health.am] The electrocardiogram evidenced sinus rhythm with 100 bpm, peaked P wave and inverted T wave from V1 to V3.[scielo.br]

  • Acute Cor Pulmonale

    The most typical ECG findings in emphysema are: Rightward shift of the P wave axis with prominent P waves in the inferior leads and flattened or inverted P waves in leads[lifeinthefastlane.com] Other ECG findings in PE include right bundle-branch block, right axis deviation, atrial fibrillation, and T-wave changes ( 2, 3 ).[ispub.com] ECG dominant R wave in lead V1 10 defined as an R wave height 7 mm or R/S 1 accompanied by dominant S waves in lead V6 right axis deviation secondary repolarization abnormalities[radiopaedia.org]

  • Left Anterior Fascicular Block

    Of the few P-waves we can see, their shape is uniformly round. They appear to be upright in v1 but possibly inverted in v2–6.[bjcardio.co.uk] The electrical axis will be more positive than 90 (right axis deviation).[ecgwaves.com] In your differential, consider posterior fascicular blocks with right axis deviation and consider anterior fascicular blocks with left axis deviation.[inside.fammed.wisc.edu]

  • Biventricular Hypertrophy

    Specifically, increase in Q wave size, abnormalities in the P wave as well as giant inverted T waves are indicative of significant concentric hypertrophy.
