93 Possible Causes for Left Axis Deviation, Prolonged PR Interval

  • Hyperkalemia

    ., prolonged PR interval, wide QRS complex) as an alternative to 10 units of short acting insulin.[ncbi.nlm.nih.gov] Left axis deviation. Absent P waves. Example 6 Hyperkalaemia: Sine wave appearance with severe hyperkalaemia (K 9.9 mEq/L). Example 7 Hyperkalaemia: Huge peaked T waves.[lifeinthefastlane.com] , prolonged PR interval, prolonged QRS interval, loss of P wave, sine waves and finally ventricular fibrillation (see ECG guideline for normal values for age) ECG CHANGES[starship.org.nz]

  • Morbid Obesity

    Relationships between abdominal obesity and glucose tolerance disorders have been well documented. There are also many reports concerning body weight gain during insulin therapy. On the other hand, there are reports pertaining to the effectiveness of surgical treatment of obesity and related type 2 diabetes. The[…][ncbi.nlm.nih.gov]

  • Ostium Primum Atrial Septal Defect

    In primum defects left axis deviation is seen in most patients with an axis of -30 degrees and very few patients have right axis deviation.[en.wikipedia.org] Complete heart block may be revealed in ostium primum type Large ASD may have prolonged PR interval 18.[slideshare.net] Individuals with atrial septal defects may have a prolonged PR interval (a first degree heart block).[marmur.com]

  • Cardiac Amyloidosis

    Electrocardiogram depicted low voltage in limb leads and a prolonged PR interval.[ncbi.nlm.nih.gov]

  • Amyloidosis

  • Bifascicular Block

    Perioperative risk of complete heart block in patients with bifascicular block and prolonged PR interval.[thorax.bmj.com] […] with right bundle-branch block and left axis deviation (56% or 55/98).[ncbi.nlm.nih.gov] To make it trifascicular, one also needs to have a prolonged PR interval. Here's a block from the author's own collection.[derangedphysiology.com]

  • First-Degree Atrioventricular Block

    Frequently, there is left axis deviation, especially if the hypertrophy is confined to the left ventricle.[ecgguru.com] Data is sparse on an extremely prolonged PR interval associated with Atrioventricular Dissociation and Pseudo-Pacemaker Syndrome.[ncbi.nlm.nih.gov] Left anterior fascicular block ( LAFB ) Malfunction of the anterior fascicle of the left Tawara branch Axis deviation to the left: extreme left axis deviation and persistent[amboss.com]

  • Atrial Septal Defect

    When an ostium primum atrial defect is present, the ECG reveals left axis deviation.[healio.com] Complete heart block may be revealed in ostium primum type Large ASD may have prolonged PR interval 18.[slideshare.net] In ostium primum ASD, it shows left axis deviation and right bundle branch block. In sinus venosus ASD, it shows left axis deviation and a negative P wave in lead III.[symptoma.com]

  • Cardiomyopathy

    Biatrial enlargement Left ventricular hypertrophy or biventricular enlargement Left bundle branch block ( RBBB can also occur). Left axis deviation.[lifeinthefastlane.com] deviation (right or left) Conduction abnormalities (P-R prolongation, bundle-branch block) Sinus bradycardia with ectopic atrial rhythm Atrial enlargement Abnormal and prominent[emedicine.com] There are some signs of left atrial enlargement — leftward deviation of the P wave axis (positive P waves in I and aVL, inverted in III and aVF) and prolongation of the terminal[lifeinthefastlane.com]

  • AV Block Mobitz I

    Left anterior fascicular block ( LAFB ) Malfunction of the anterior fascicle of the left Tawara branch Axis deviation to the left: extreme left axis deviation and persistent[amboss.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 conducted basic PR interval is usually normal in ttype 2 AV block. In wenkebach the PR interval is usually prolonged.(Not always though![drsvenkatesan.com]
