50 Possible Causes for Poor R Wave Progression, Right Axis Deviation

  • Chronic Obstructive Pulmonary Disease

    ECG poor R wave progression requires an R wave in V3 3 mm clockwise rotation of the heart secondary to hyperinflation results in a delayed precordial transition zone the lead[radiopaedia.org] deviation 110 without right bundle branch block; or some combination of these.[merckmanuals.com] […] ventricular hypertrophy right axis deviation dominant R wave in V1 with an amplitude 7mm often associated with "P pulmonale" ( right atrial enlargement ) multifocal atrial[radiopaedia.org]

  • Asthma

    Electrocardiographic signs of right heart strain such as right axis deviation, clockwise rotation, and evidence of right ventricular hypertrophy may be observed in acute,[ncbi.nlm.nih.gov]

  • Anterior Myocardial Infarction

    The remarkable feature is the poor R wave progression in the V1 and V2 leads and the ST elevation and T wave changes in leads V1 to V4 and I and aVL.[wikidoc.org] […] precordial R waves) Pulmonary emphysema and cor pulmonale (loss of R waves V1-3 and/or inferior Q waves with right axis deviation) Left anterior fascicular block (may see[ecg.utah.edu] This is a cause of poor R wave progression , or PRWP.[healio.com]

  • Pulmonary Embolism

    P pulmonale, right and left axis deviation, S 1 S 2 S 3 and S 1 Q 3 T 3 patterns, low voltage and clockwise rotation were specific, but not sensitive for APE.[ncbi.nlm.nih.gov] axis deviation, right bundle branch block (RBBB), or deep S-waves in I with Q waves in III and inverted T waves in III ('S1,Q3,T3' pattern).[patient.info] Right axis deviation and S 1 Q 3 T 3 pattern were observed in only APE. Low voltage was more frequent in APE and TC. However, the frequencies of these findings were low.[ncbi.nlm.nih.gov]

  • Recurrent Pulmonary Embolism

  • Acute Massive Pulmonary Embolism

    His electrocardiogram showed wide-complex atrial fibrillation with rapid ventricular rate of 182, right axis deviation, right ventricular hypertrophy and inferior Q waves[epmonthly.com] […] heart strain), - right axis deviation - s wave (I and aVL) 1.5mm - Q wave in III and aVF - p pulmonale - RBBB CXR: rules out other pathology, focal oligaemia, wedge density[lifeinthefastlane.com] axis deviation T-wave inversion in the right precordial leads /- the inferior leads is seen in up to 34% of patients and is associated with high pulmonary artery pressures[radiopaedia.org]

  • Acute Cor Pulmonale

    Rightward shift of the QRS axis towards 90 degrees (vertical axis) or beyond ( right axis deviation ).[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]

  • Infiltrative Cardiomyopathy

    The electrocardiogram showed normal sinus rhythm, QS waves in the inferior leads, poor R progression in the precordial leads and T-wave inversion in I and aVL ( Figure 1 )[revportcardiol.org] Against it was the ECG showing poor R-wave progression and echocardiographic findings suggestive of an infiltrative disease, with symmetric biventricular wall thickening and[revportcardiol.org]

  • Right Ventricular Outflow Obstruction

    BACKGROUND: Vector flow mapping (VFM) enables direct visualization of flow pattern and estimation of flow volume. The aim of this study was to determine its accuracy in the quantification of pulmonary regurgitation (PR) in congenital heart patients after repair of right ventricular (RV) outflow obstruction.[…][ncbi.nlm.nih.gov]
