216 Possible Causes for Incomplete Right Bundle Branch Block

  • Ostium Primum Atrial Septal Defect

    When you suspect a patient has an ASD based on the findings of an incomplete Right Bundle Branch Block with a rSr' or rSR' the next thing you should do is examine the frontal[en.wikipedia.org] Right ventricle hypertrophy markers or incomplete right bundle branch block may be present.[symptoma.com] Features also seen on the EKG include Right Atrial Enlargement, PR prolongation and advanced AV block.[en.wikipedia.org]

  • Secondary Cardiomyopathy

    A previous ECG (two years ago) showed incomplete right bundle branch block morphology but no other abnormality.[radcliffecardiology.com] Discussion The admission ECG shows sinus tachycardia at a rate of 148bpm, incomplete right bundle branch block, ST-segment depressions in the inferior and anterolateral leads[radcliffecardiology.com]

  • Conduction Disorder of the Heart

    right bundle branch block.[healio.com] The disease is transmitted as an autosomal dominant disorder with incomplete penetrance.[healio.com] Roberts Liu and colleagues have identified three families (one of Lebanese and two of French origin) with isolated conduction defects consisting primarily of complete or incomplete[healio.com]

  • Cor Pulmonale

    ECG shows the following changes: In acute pulmonary heart disease : right axial deviation, complete or incomplete right bundle branch block, sinus tachycardia, reversal of[doctortipster.com] […] deviation and incomplete right bundle branch block Changes in cardiac conduction due to right-sided hypertrophy Echocardiography Normal heart size To show ventricular hypertrophy[medical-dictionary.thefreedictionary.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 Hypertension

    Right axis deviation (short arrow), increased P-wave amplitude in lead II (black arrowhead), and incomplete right bundle branch block (white arrowhead) are highly specific[aafp.org] […] but lack sensitivity for the detection of right ventricular hypertrophy. 12 FIGURE 1 Electrocardiogram demonstrating the changes of right ventricular hypertrophy (long arrow[aafp.org] View/Print Figure FIGURE 1 Electrocardiogram demonstrating the changes of right ventricular hypertrophy (long arrow) with strain in a patient with primary pulmonary hypertension[aafp.org]

  • Atrial Septal Defect

    The impact of incomplete right bundle branch block (IRBBB) and ASD diameter (  5 and  5 mm) on ASD diagnosis were also explored.[ncbi.nlm.nih.gov] bundle branch block pattern (rsR' in V1), and right axis deviation.[patient.info] A common finding in the ECG is the presence of incomplete right bundle branch block , which is so characteristic that if it is absent, the diagnosis of ASD should be reconsidered[en.wikipedia.org]

  • Right Ventricular Hypertrophy

    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] bundle branch block in the right precordial chest leads may signal the development of RVH In the limb leads right axis deviation develops and at times prominent Q waves simulating[wikidoc.org] Other abnormalities caused by RVH Right bundle branch block (complete or incomplete).[lifeinthefastlane.com]

  • Recurrent Pulmonary Embolism

    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] EKG showed right axis deviation, a new incomplete right bundle branch block (IRBBB), clockwise rotation, and right heart strain with inverted T waves in V1–V4 ( Figure 2 )[nature.com] […] interval 0.24 sec), an incomplete right bundle branch block and non-specific ST-segment abnormalities: 1 mm ST elevations in DI, DII and aVL. ( Fig. 1 ) The chest radiography[tmj.ro]

  • Patent Ductus Arteriosus

    His chest X-ray showed cardiomegaly and enlargement of the left pulmonary hilum, and an electrocardiogram revealed sinus tachycardia with incomplete right bundle branch block[elsevier.pt]

  • Secondary Pulmonary Hypertension

    Right axis deviation (short arrow), increased P-wave amplitude in lead II (black arrowhead), and incomplete right bundle branch block (white arrowhead) are highly specific[aafp.org] […] but lack sensitivity for the detection of right ventricular hypertrophy. 12 FIGURE 1 Electrocardiogram demonstrating the changes of right ventricular hypertrophy (long arrow[aafp.org] View/Print Figure FIGURE 1 Electrocardiogram demonstrating the changes of right ventricular hypertrophy (long arrow) with strain in a patient with primary pulmonary hypertension[aafp.org]
