How many segments is the left ventricle divided into when assessing wall motion at the basal level?

The left ventricle is divided into six segments when assessing wall motion at the basal level. This division allows for a detailed evaluation of the heart's function and helps to identify areas of impaired contractility or other abnormalities.

In clinical practice, the left ventricle is typically assessed using the American Heart Association (AHA) 17-segment model. At the basal level, this model divides the left ventricle into six segments: the anterior, anteroseptal, septal, inferior, inferoseptal, and lateral segments. This segmentation provides a thorough understanding of regional wall motion and allows for effective diagnosis and management of cardiac conditions.

Understanding how these segments are defined and evaluated is crucial for interpreting echocardiographic findings accurately. This model is commonly used in echocardiography to assess the left ventricle's structural integrity and function, making it essential for any clinical assessment related to cardiac health.
