92 Possible Causes for Incomplete Right Bundle Branch Block, Right Axis Deviation, Sudden Death

  • Cor Pulmonale

    Right axis deviation and low voltage may be noted in patients with pulmonary emphysema.[health.am] In the United States, approximately 25,000 sudden deaths occur per year from heart failure associated with pulmonary emboli.[nursing.unboundmedicine.com] […] axis deviation due to right ventricular hypertrophy Incomplete or complete right bundle branch block In some cases, P pulmonale S1Q3 pattern in acute cor pulmonale Chest[amboss.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] METHODS: We present an unusual case of sudden death owing to acute pulmonary embolism after undergoing total extraperitoneal inguinal hernia repair.[ncbi.nlm.nih.gov] […] and complete right bundle branch block [RBBB], and T-wave inversion in leads V1-V4, plus ST elevation in lead aVR and atrial fibrillation suggestive of RV strain from acute[ncbi.nlm.nih.gov]

  • Acute Cor Pulmonale

    Rightward shift of the QRS axis towards 90 degrees (vertical axis) or beyond ( right axis deviation ).[lifeinthefastlane.com] death.[ncbi.nlm.nih.gov] […] or complete right bundle branch block (2) S waves in leads I and aVL of 1.5 mm (3) a shift in the transition zone in the precordial leads to V5 (4) Q waves in leads III and[ispub.com]

  • Pulmonary Hypertension

    Surface electrocardiogram showed right atrial and ventricular overload with right axis deviation.[ncbi.nlm.nih.gov] Sudden cardiac death.[patient.info] These signs include the following: Right-axis deviation R/S ratio greater than 1 in lead V1 Right atrial enlargement as indicated by an increased P-wave amplitude in lead[emedicine.com]

  • Right Ventricular Hypertrophy

    Example 4 Right ventricular hypertrophy in a patient with arrhythmogenic right ventricular cardiomyopathy (ARVC): Right axis deviation.[lifeinthefastlane.com] death due to cardiac tamponade. ventricular septal defect a congenital heart defect in which there is persistent patency of the ventricular septum in either the muscular[medical-dictionary.thefreedictionary.com] In contrast, when an incomplete right bundle branch block exists, the rSR' pattern is a relatively sensitive but nonspecific predictor of RVH.[ncbi.nlm.nih.gov]

  • Cardiomyopathy

    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] A thorough family history of juvenile sudden death, ventricular arrhythmias and ICD implants should always be sought.[ncbi.nlm.nih.gov] Right axis deviation suggests associated right ventricular hypertrophy (i.e. biventricular enlargement ).[lifeinthefastlane.com]

  • Chronic Obstructive Pulmonary Disease

    […] 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] (including sudden death) and all-cause mortality.[doi.org] deviation 110 without right bundle branch block; or some combination of these.[merckmanuals.com]

  • Eisenmenger Syndrome

    Diagnostic methods Diagnosis is based on the clinical features, pulse oximetry findings, an abnormal electrocardiogram (right axis deviation, right ventricular hypertrophy[orpha.net] There were 21 (13%) documented deaths, of which 8 (5%) were sudden death.[ncbi.nlm.nih.gov] Longstanding pulmonary hypertension may cause dissection, which may lead to sudden death or pulmonary hemorrhage often seen in patients with Eisenmenger syndrome.[ncbi.nlm.nih.gov]

  • Recurrent Pulmonary Embolism

    Focal oligemia, cardiomegaly and plump pulmonary arteries on chest X-ray films, right axis deviation, clockwise rotation, ST-segment depression and T-wave inversion on electrocardiograms[ncbi.nlm.nih.gov] About 15% of all cases of sudden death are attributable to PE. [2] While PE may present with syncope, less than 1% of syncope cases are due to PE. [17] On physical examination[en.wikipedia.org] Review of EKGs showed a trend of increasing right axis deviation with recovery and recurrences during the previous 9 years and a current incomplete right bundle branch block[ncbi.nlm.nih.gov]

  • Ostium Primum Atrial Septal Defect

    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] death.[clinicalgate.com] Right ventricle hypertrophy markers or incomplete right bundle branch block may be present.[symptoma.com]
