Answer: Left Axis Deviation (LAD) refers to the pattern of electrical activation that occurs in the heart. LAD is an EKG-specific finding and not necessarily indicative of any specific cardiovascular condition. In fact, LAD is the most common EKG abnormality observed in adults, occurring in almost 10% of the adult population.
Right Axis Deviation (RAD) is a heart condition wherein the electrical conduction of the heart has an electrical axis greater than +90Â° (or sometimes greater than +105Â°) on a 12-lead ECG.
