25 Possible Causes for Complete Left Bundle Branch Block, Short PR Interval, Supraventricular Tachycardia

  • Myocardial Infarction

    The exclusion criteria included an inability to provide informed consent, dementia, complete left bundle-branch block, cardiogenic shock, and a higher-than-normal risk of[dx.doi.org] tachycardia; ventricular tachycardia, significant ST segment depression or elevation (more than 2 mm); significant ischemia on the echocardiogram (more than 1 segment).[dx.doi.org] ., complete left bundle branch block, paced rhythm, accessory pathway, left ventricular hypertrophy, digitalis use, and resting ST-segment abnormalities). 4 From a prognostic[web.archive.org]

  • Acute Myocardial Infarction

  • Lown-Ganong-Levine Syndrome

  • Preexcitation Syndrome

  • Right Bundle Branch Block

    There are several possible explanations for the intermittent shift in the QRS axis in the presence of complete left bundle branch block.[ncbi.nlm.nih.gov] In patients with Ebstein's anomaly and supraventricular tachycardia, the absence of right bundle branch block (RBBB) in sinus rhythm is a highly sensitive and specific indicator[ncbi.nlm.nih.gov] PR interval) and incomplete right bundle branch block (IRBBB).[ncbi.nlm.nih.gov]

  • Left Bundle Branch Block

    Conversely, any supraventricular tachycardia with left bundle-branch block is typically associated with a normal or leftward QRS axis.[ncbi.nlm.nih.gov] Complete left bundle branch block (LBBB) is established according to standard electrocardiographic criteria.[ncbi.nlm.nih.gov] On superficial evaluation, the ECGs suggest the presence of an alternating bundle branch block, but on a closer look it is seen that the PR intervals of the RBBB morphology[casesjournal.biomedcentral.com]
