As per the report you have shared, there is normal sinus rhythm, along with normal intervals. [1] Also, a study found that LAE can occur as a consequence of atrial fibrillation (AF),[3] although another study found that AF by itself does not cause LAE.

There are numerous pathological conditions that cause sinus bradycardia. The primary form of Mitral Valve Prolapse is seen frequently in people with Marfan's Syndrome or other inherited connective tissue diseases, but is most often seen in people with no other form of heart disease. T wave inversions preceded by ST-segment depressions are suggestive of underlying pathology; ST segment depressions should always be considered abnormal; upright T wave in aVR in the context of T wave inversion in V5/V6 is suggestive of pathology involving the left ventricular apex.
