143 Possible Causes for Left Bundle Branch Block, Prolonged PR Interval

  • Ostium Primum Atrial Septal Defect

    The 12-lead ECG will show an incomplete right bundle branch block and left axis deviation (in contrast to the secundum ASD which has a right axis deviation).[healio.com] Complete heart block may be revealed in ostium primum type Large ASD may have prolonged PR interval 18.[slideshare.net] Right ventricle hypertrophy markers or incomplete right bundle branch block may be present.[symptoma.com]

  • First-Degree Atrioventricular Block

  • Acute Myocarditis

    One patient had left bundle-branch block. Peak serum creatine kinase levels were elevated in six of the eight patients (range, 150 to 1518 units per liter).[nejm.org] bundle branch block (LBBB) are associated with higher rates of cardiac death or heart transplantation Radiology description Chest Xray: cardiomegaly due to chamber dilation[pathologyoutlines.com] […] infarction Atrial or ventricular conduction delays, supraventricular and ventricular arrhythmias can occur in patients with myocarditis The presence of Q waves or a new left[pathologyoutlines.com]

  • 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] A transthoracic echocardiogram revealed a PDA with left-to-right shunt (pulmonary/systemic flow [Qp/Qs] ratio of 1.6), left ventricular ejection fraction of 60% and enlargement[elsevier.pt]

  • Sinoatrial Block

    Abstract A case of alternating second degree sinoatrial block and left bundle branch block is described.[ncbi.nlm.nih.gov] This is different than a first-degree atrioventricular, or AV, block, which shows a prolonged PR interval.[healio.com] Mobitz Type 1 (Wenckebach) • Gradual prolongation of PR interval until nonconducted p wave • RP-PR reciprocity • Lengthening of the PR interval at progressively shorter decrements[slideshare.net]

  • Diphtheritic Myocarditis

Samik Wahab A.[jurnal.ugm.ac.id] The following ECG changes may be noted in patients with rheumatic fever : [1] Sinus tachycardia or bradycardia depending on vagal tone Prolongation of PR interval Variable[wikidoc.org] The myocarditis manifested with severe conduction disturbances including left bundle-branch block and high grade second degree atrioventricular block leading to Adams-Stokes[ncbi.nlm.nih.gov]

  • AV Block Mobitz II

    In addition, there is a LEFT BUNDLE BRANCH BLOCK.[ecgguru.com] Commonly used terminology includes: First degree AV block – Delayed conduction from the atrium to the ventricle (defined as a prolonged PR interval of 200 milliseconds) without[uptodate.com] Every-other-P wave conducts – as determined by the presence of a fixed ( albeit prolonged ) PR interval preceding each QRS complex on the tracing.[ecg-interpretation.blogspot.com]

  • AV Block Mobitz I

    In addition, there is a LEFT BUNDLE BRANCH BLOCK.[ecgguru.com] The hallmark of Mobitz type 1 block is the gradual prolongation of PR intervals before a block occurs. Mobitz type 2 block has constant PR intervals before blocks occur.[ecgwaves.com] The first non-conducted P wave is indicated with an arrow. the PR interval of conducted P waves is constant in this lady there is a long PR interval (and left bundle branch[ecglibrary.com]
