Mastering Cardiac Axis Deviation: A Guide to ECG Lead Interpretation

ECG / EKG anatomy-note-512-512-png-1-96x96 Tag Template - Week PRO Anatomy Note -
The electrical axis of the heart is a fundamental diagnostic parameter in electrocardiography that describes the average direction of electrical depolarization as it spreads through the ventricles. By examining the morphology and polarity of the QRS complex in standard limb leads I, II, and III, healthcare providers can determine the mean electrical vector of the heart. Accurately identifying whether a patient has a normal axis or a specific deviation is critical for diagnosing underlying conditions such as ventricular hypertrophy, conduction blocks, or myocardial infarction.
