LAHB in the medical field refers to a Left Anterior Hemiblock, also known as a Left Anterior Fascicular Block (LAFB).
Understanding Left Anterior Hemiblock (LAHB)
LAHB occurs when the anterior fascicle of the left bundle branch in the heart is unable to conduct electrical impulses properly. This disruption affects the heart's electrical conduction system, leading to specific changes observable on an electrocardiogram (ECG).
Diagnosing LAHB
According to the provided reference, the diagnostic criteria for LAHB (or LAFB) on an ECG include:
- Left Axis Deviation: This means the electrical axis of the heart is shifted to the left, typically at least -45 degrees.
Impact of LAHB
LAHB, by itself, may not always be clinically significant. However, it can occur in conjunction with other heart conditions. Identifying LAHB through ECG analysis is crucial for understanding a patient's overall cardiac health and guiding appropriate treatment strategies.
