28 Possible Causes for Inverted P Wave, Mitral Valve Insufficiency

  • Cardiomyopathy

    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] […] portion of the P wave in V1.[lifeinthefastlane.com] […] an interventricular conduction delay mimicking LBBB — however, this is not LBBB as the morphology is not typical and there are small Q waves in V5-6 ( the presence of Q waves[lifeinthefastlane.com]
