Left axis deviation

Left Axis Deviation is a condition related to the electrical activity of the heart. It is often identified through an electrocardiogram (ECG), which measures the heart's electrical conduction system.

Overview

Left Axis Deviation (LAD) is a term used in the field of cardiology to describe the change in the electrical axis of the heart. This deviation is typically between -30 and -90 degrees. It is often associated with various cardiac conditions such as left ventricular hypertrophy, inferior myocardial infarction, and Wolff-Parkinson-White syndrome.

Causes

The causes of Left Axis Deviation can be physiological or pathological. Physiological causes include athletic heart syndrome and natural aging. Pathological causes include conditions such as heart block, cardiomyopathy, and myocardial infarction.

Diagnosis

Diagnosis of Left Axis Deviation is typically made through an electrocardiogram (ECG). The ECG will show a deviation of the electrical axis to the left of the normal axis. Other diagnostic tests may include echocardiography and cardiac MRI.

Treatment

Treatment for Left Axis Deviation depends on the underlying cause. If the deviation is due to a heart condition, treatment may include medication, lifestyle changes, or in some cases, surgery. It is important to consult with a cardiologist for appropriate treatment options.
