Learn about left axis deviation (LAD), a condition where the electrical axis of the heart points to the left in the frontal plane. Find out the causes, symptoms, and treatment of LAD and how to determine it on ECG.
8 paź 2024 · Learn how to recognise and interpret left axis deviation (LAD) on the ECG, a condition where the QRS axis is less than -30 degrees. Find out the causes, examples, and related topics of LAD from the LITFL ECG Library.
Left axis deviation is when the QRS axis is between -30° and -90º on the EKG. It may be due to normal variation, left ventricular hypertrophy, left anterior fascicular block, left bundle branch block, inferior wall myocardial infarction, hyperkalemia, emphysema, or congenital heart disease.
In electrocardiography, left axis deviation is a condition where the mean electrical axis of ventricular contraction of the heart lies in a frontal plane direction between −30° and −90°. This is reflected by a QRS complex positive in lead I and negative in leads aVF and II.
5 dni temu · Left axis deviation (LAD) is when the QRS axis is less than -30°, indicating left ventricular hypertrophy or other pathology. Learn how to estimate QRS axis using different methods and see examples of LAD causes and ECGs.
8 sty 2024 · Identify the key components of electrical axis deviation on an electrocardiogram. Differentiate between right-axis deviation and left-axis deviation based on electrocardiogram patterns. Apply knowledge of vector analysis to interpret electrocardiograms and determine the electrical axis.
