Left anterior fascicular block
Left Anterior Fascicular Block
Left Anterior Fascicular Block (pronunciation: left an-teer-ee-or fas-sik-yuh-lar blok), often abbreviated as LAFB, is a condition characterized by the blockage or delay of electrical impulses in the anterior fascicle of the left bundle branch in the heart's conduction system.
Etymology
The term is derived from the Latin words 'laevus' meaning 'left', 'anterior' meaning 'front', 'fasciculus' meaning 'small bundle', and 'blocare' meaning 'to block'.
Definition
In LAFB, the electrical impulses that control the heartbeat are partially or completely blocked in the anterior fascicle of the left bundle branch. This can lead to an abnormal heart rhythm, known as arrhythmia, and can potentially cause other heart-related complications.
Symptoms
Symptoms of LAFB may include dizziness, shortness of breath, chest pain, and fatigue. However, some individuals with LAFB may not experience any symptoms.
Diagnosis
LAFB is typically diagnosed through an electrocardiogram (ECG), which can detect abnormalities in the heart's electrical activity. Other diagnostic tests may include a stress test, echocardiogram, or cardiac catheterization.
Treatment
Treatment for LAFB depends on the underlying cause and severity of the condition. It may include medications to manage symptoms or prevent complications, and in some cases, a pacemaker may be required to regulate the heart's rhythm.
