263 Possible Causes for Left Bundle Branch Block, Wolff-Parkinson-White Syndrome

  • Cardiomyopathy

  • Mitral Valve Prolapse

    Miscellaneous Wolff-Parkinson-White syndrome and von Willebrand disease may also lead to MVP.[emedicine.medscape.com] bundle branch block/right axis deviation morphology was induced.[ncbi.nlm.nih.gov] […] ventricular function decompensation; Complex ventricular arrhythmia; QT interval significantly prolonged; ventricular late potential positive; atrial flutter or fibrillation with Wolff-Parkinson-White[healthfrom.com]

  • Wolff-Parkinson-White Syndrome

    Tachycardia associated with Wolff-Parkinson-White syndrome can occur occasionally even when prophylactic treatment is administered.[ncbi.nlm.nih.gov] Can look like right bundle branch block Type B – negative delta wave in V1 and V2, positive in other precordial leads. Can look like left bundle branch block.[almostadoctor.co.uk] It can be mistaken for left bundle branch block or left ventricular hypertrophy with strain.[ecgmedicaltraining.com]

  • Ebstein Malformation

    syndrome. 3 Associated cardiac lesions are uncommon 4 and ventricular septal defect (VSD) is a very rare association. 5-7 We reported an infant with severe EA, VSDs and Wolff-Parkinson-White[eplabdigest.com] The abnormality is often associated with right-to-left atrial shunting and Wolff-Parkinson-White syndrome .[medical-dictionary.thefreedictionary.com] […] relative to the anterior mitral leaflet, but always 2 body surface area. 2 Overall, approximately 14–20% of EA patients will have one or more accessory conduction pathways with Wolff-Parkinson-White[eplabdigest.com]

  • Adenosine

    Services Adenosine is a cardiac drug that is used for the treatment of paroxysmal supraventricular tachycardia (PSVT) including that associated with accessory bypass tracts (Wolff-Parkinson-White[fda.gov] Presenting electrocardiogram (ECG) showed an old left bundle branch block and T-wave inversions in lateral leads (QTc 494ms) with no significant electrolyte abnormalities.[ncbi.nlm.nih.gov] Wolff-Parkinson-White syndrome). Adenosine has also been used to treat fetal arrhythmias.[medicinesinpregnancy.org]

  • Hypoaldosteronism

    Left ventricular hypertrophy, Wolff-Parkinson-White syndrome and other cardiac conduction abnormalities, as well as heart failure have been reported in these patients (1,12[scielo.br] bundle branch block and hyporeninemic hypoaldosteronism (hyperkalemic left bundle branch block).

  • Pulsus Alternans

    Conduction alternans may be seen in the setting of myocardial ischemia, atrial fibrillation, Wolff-Parkinson-White syndrome, rheumatic heart disease, acute pulmonary embolism[emedicine.medscape.com] Pulsus alternans was caused by 2:1 left bundle branch block in a patient with a left ventricular ejection fraction of 50% and normal coronary arteries.[ncbi.nlm.nih.gov] […] as a marker for orthodromic atrioventricular (AV) reentrant tachycardia using an accessory pathway as a retrograde limb Etiology Myocardial Ischemia Atrial Fibrillation Wolff-Parkinson-White[mdnxs.com]

  • Flecainide

    Some asymptomatic patients with Wolff-Parkinson-White syndrome have severe left ventricular dyssynchrony and dysfunction.[ncbi.nlm.nih.gov] The patient presented with a mild mitral regurgitation and normal left ventricular function. He had incomplete left bundle branch block with left-axis deviation.[ncbi.nlm.nih.gov] In the setting of flecainide toxicity, supraventricular tachycardia can manifest as a bizarre right or left bundle branch block, sometimes with a northwest axis, and can easily[ncbi.nlm.nih.gov]

  • Left Bundle Branch Block

  • Antiarrhythmic Agent

    A patient with the Wolff-Parkinson-White syndrome had an inducible orthodromic atrioventricular (AV) tachycardia prior to flecainide, but only an antidromic tachycardia was[ncbi.nlm.nih.gov] bundle branch block morphology of the patient’s right ventricular paced rhythm (70 beats/min) ( A) ; ventricular tachycardia originating from the left ventricle ( B ); and[mja.com.au] These agents are also the drugs of choice in patients with Wolff-Parkinson-White syndrome.[pharmaceutical-journal.com]
