What does LAFB refer to in cardiac terms?

LAFB stands for Left Anterior Fascicular Block, which is a specific type of conduction block in the heart's electrical system. In this condition, there is a delay or blockage in the conduction of electrical impulses along the left anterior fascicle of the left bundle branch. This can be identified on an electrocardiogram (ECG) by specific changes in the electrical patterns.

The significance of identifying LAFB lies in its relationship with various cardiac conditions. It can often be seen in patients with underlying heart diseases, particularly those with left ventricular hypertrophy or myocardial infarction. Understanding LAFB helps healthcare professionals interpret ECGs accurately and assess the patient's heart function, guiding further evaluation and treatment.
