72 Possible Causes for Incomplete Right Bundle Branch Block, Right Axis Deviation, Tachyarrhythmia

  • Cor Pulmonale

    Right axis deviation and low voltage may be noted in patients with pulmonary emphysema.[] Life-threatening ventricular tachyarrhythmias are less common.[] […] deviation and incomplete right bundle branch block Changes in cardiac conduction due to right-sided hypertrophy Echocardiography Normal heart size To show ventricular hypertrophy[]

  • Acute Cor Pulmonale

    Rightward shift of the QRS axis towards 90 degrees (vertical axis) or beyond ( right axis deviation ).[] Atrial tachyarrhythmias should be slowed with digoxin, amiodarone, or diltiazem.[] […] 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[]

  • 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.[] […] 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[] […] 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[]

  • 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[] […] and myocardial ischaemia. 8 Although tachyarrhythmias are often considered benign, they confer an increased risk of embolic strokes and sudden death in susceptible cardiac[] deviation 110 without right bundle branch block; or some combination of these.[]

  • 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[] Cardiovascular examination may show atrial fibrillation or other tachyarrhythmia.[] 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[]

  • 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.[] Complications: Growth failure Atrial tachyarrhythmia Pulmonary hypertension Paradoxical emboli to brain and body Treatment: Closure via surgery or percutaneous catheterization[] […] pulmonary hypertension. 36 Older children and young adults come to light because an x-ray discloses the scimitar sign and the hypoplastic right lung or because of an atrial tachyarrhythmia[]

  • Right Ventricular Hypertrophy

    Example 4 Right ventricular hypertrophy in a patient with arrhythmogenic right ventricular cardiomyopathy (ARVC): Right axis deviation.[] After CMR imaging, 15 patients developed cardiovascular events that included admission for heart failure, ventricular tachyarrhythmia/fibrillation, stroke, and sudden cardiac[] In contrast, when an incomplete right bundle branch block exists, the rSR' pattern is a relatively sensitive but nonspecific predictor of RVH.[]

  • Patent Foramen Ovale

    deviation of the QRS complex while those with a secundum ASD have a right axis deviation of the QRS complex.[] Frequency of atrial tachyarrhythmias following transcatheter closure of patent foramen ovale. J Invasive Cardiol 2006 ;18: 365 - 368 30.[] 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[]

  • Pulmonary Hypertension

    Surface electrocardiogram showed right atrial and ventricular overload with right axis deviation.[] Syncope can also result from ventricular tachyarrhythmias secondary to an ischaemic ventricle, but no such arrhythmias were documented.[] In that series, supraventricular tachyarrhythmias occurred with an annual incidence of 2.8%.[]

  • Ebstein Malformation

    Right axis deviation and Right Bundle branch Block are frequently observed as well.[] The defect involves both the right ventricle and the tricuspid valve, and can lead to cardiomyopathy and tachyarrhythmias ICD-9-CM Volume 2 Index entries containing back-references[] There may be tall and broad P waves (right atrial enlargement) and complete or incomplete right bundle-branch block. The R waves in leads V1 and V2 are small.[]
