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

  • 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] […] may also be seen. 20 The presence of Q waves, a new left bundle branch block and prolonged QRS duration of 120msec is associated with higher rates of cardiac death or heart[jpma.org.pk]

  • First-Degree Atrioventricular Block

  • Cardiac Amyloidosis

    ECG  Low-voltage limb leads, often with an unusually rightward axis  First-degree AV block  Q waves in V1 to V3  Left bundle branch block is rare in AL amyloidosis 11[slideshare.net] Electrocardiogram depicted low voltage in limb leads and a prolonged PR interval.[ncbi.nlm.nih.gov] […] ventricular outflow tract and aortic valve in MRI Fig. 5 ECG at admission shows atrial fibrillation at 78 bpm, left bundle branch block and signs of left ventricular hypertrophy[bmccardiovascdisord.biomedcentral.com]

  • Restrictive Cardiomyopathy

  • Sinoatrial Block

    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]

  • Mexiletine
