Left Axis Deviation in Electrocardiogram with Normal QRS Duration in Ambulatory Adults without Cardiac Symptoms: A Possible Marker of Glucose Intolerance

Introduction: We are increasingly noticing isolated left axis deviation (LAD) in electrocardiogram in younger people with diabetes without obvious heart disease and association of LAD with glucose intolerance has not been explicitly raised before. We planned a study of ambulatory adults with borderline (0o to –30o) and moderate-to-marked (
