73 Possible Causes for Right Bundle Branch Block, Ventricular Bigeminy

  • Cardiomyopathy

    Frequent ventricular ectopics and ventricular bigeminy (seen with severe DCM). Ventricular dysrhythmias ( VT / VF ).[] […] precordial leads ( V 1-3 ) possibly epsilon wave (at the end of a widened QRS complex ) Right bundle branch block Echocardiography and/or cardiac MRI Right ventricular enlargement[] , inverted T waves V 2 , V 3 *) in absence of right bundle branch block Echocardiography Localized RV aneurysm, isolated RV failure Magnetic Resonance Imaging Fatty infiltration[]

  • Premature Ventricular Contraction

    Example 3) Ventricular Bigeminy ECG (Example 1) Ventricular Bigeminy ECG (Example 2) Ventricular Bigeminy ECG (Example 3) Ventricular Trigeminy ECG (Example 1) Ventricular[] branch block (LBBB), right bundle branch block (RBBB), atrial premature contraction (APC), and paced beat (PB) rhythms.[] When describing PVCs or the morphology of nonsustained ventricular tachycardia, the terms “left bundle-branch block pattern” and “right bundle-branch block pattern” refer[]

  • Acute Myocarditis

    It has also been described in a work the report of sequences of alternatively normal and Wenckebach beats with alternate and progressive right bundle branch block interpreted[]

  • Atrial Bigeminy

    The patient is in Ventricular Bigeminy. Bigeminy comes for the latin for ‘twins’.[] Manufacturer Medtronic Device PM Field Pacing Modes Patient 63-year-old man with a history of paroxysmal atrial fibrillation; full right bundle branch block pattern on the[] Block Right Bundle Branch Block Left Bundle Branch Block Left Anterior Hemiblock Left Posterior Hemiblock Normal Sinus Rhythm Atrial Premature Depolarization Premature Atrial[]

  • Acute Myocardial Infarction

    BACKGROUND New-onset extreme right axis deviation and right bundle branch block (RBBB) are rare during acute myocardial infarction (AMI), and has only been reported in several[] Right bundle branch block in anterior MI is an independent marker of poor prognosis; this is due to the extensive myocardial damage involved rather than the conduction disorder[]

  • Paroxysmal Ventricular Tachycardia

    RVOT non-sustained monomorphic ventricular tachycardia (on the left side) and LVOT ventricular bigeminy (on the right side). Figure 2.[] […] from the previous cardiac cycle, which results in a right bundle branch block pattern.[] The ECG typically shows right axis deviation, with a left bundle branch block pattern.[]

  • Premature Atrial Contractions

    This results in the premature beat displaying a right bundle branch block pattern and can be confused with a premature ventricular contraction.[] Atrial bigeminy results in decreased left ventricular function: an insight into the mechanism of PVC‐induced cardiomyopathy .[] Mostly right bundle branch block aberrancy as the RBBB has a longer refractory period. Non-conducted.[]

  • Coronary Artery Disease

    Mitral regurgitation is uncommon with left atrial myxoma. The echocardiographic assessment of presence of mitral regurgitation and its severity are impaired by the presence of left atrial myxoma. We describe an uncommon association of left atrial myxoma with coronary artery disease and mitral regurgitation. MR was[…][]

  • Bidirectional Tachycardia

    If the threshold heart rate for delayed afterdepolarizations is surpassed at a given focus in the bundle branches, ventricular bigeminy develops, and the heart rate is effectively[] Another possible pattern is alternating left and right bundle-branch block (see Figure 2 in the paper by Smith et al ).[] The tachycardia had alternating right and left bundle branch block morphology on a beat-to-beat basis and was successfully eliminated by ablating the right and left bundle[]

  • Dofetilide

    He experienced an 8-beat run of non-sustained ventricular tachycardia, frequent multifocal PVCs, and ventricular bigeminy.[] Premature ventricular contractions and right bundle branch block were evident at this dose, without changes in cardiovascular parameters.[] Of the 36 patients in Group I who started dofetilide before ablation, three stopped it prior to ablation (one for ventricular bigeminy, one for bradycardia, and one due to[]
