Left axis deviation is commonly associated with which condition?

Explanation:
Left axis deviation shows that the overall direction of ventricular depolarization is toward the left. When the left ventricle enlarges, its depolarization vector becomes stronger to the left, pulling the mean QRS axis in that direction. This makes left ventricular hypertrophy the condition most commonly linked with a leftward shift on the frontal-plane axis. While other situations can tilt the axis, LVH is the classic and most reliable association. Right axis deviation points toward right-sided problems like RVH, and while some blocks can affect axis, the hallmark link is LVH with left axis deviation.
