My father had a left anterior hemi block is it a worry what should I do.

Question

LAFB which is also known as left anterior hemiblock (LAHB) occurs when a cardiac impulse spreads first through the left posterior fascicle, causing a delay in activation of the anterior and upper parts of the LV.
Normal activation of the left ventricle (LV) proceeds down the left bundle branch, which consist of three fascicles, the left anterior fascicle, the left posterior fascicle, and the septal fascicle. The posterior fascicle supplies the posterior and inferoposterior walls of the LV, the anterior fascicle supplies the upper and anterior parts of the LV and the septal fascicle supplies the septal wall with innervation. LAFB — which is also known as left anterior hemiblock (LAHB) — occurs when a cardiac impulse spreads first through the left posterior fascicle, causing a delay in activation of the anterior and upper parts of the LV. Although there is a delay or block in activation of the left anterior fascicle there is still preservation of initial left to right septal activation as well as preservation of the inferior activation of the LV (preservation, on the EKG, of septal Q waves in I and aVL and predominantly negative QRS complex in leads II, III, and aVF). The delayed and unopposed activation of the remainder of the LV now results in a shift in the QRS axis leftward and superiorly, causing marked left axis deviation. This delayed activation also results in a widening of the QRS complex, although not to the extent of a complete LBBB.
Left Anterior Hemiblock Treatment
Treatment for left bundle branch block depends on the underlying cause.
Treatment for left bundle branch block may include:
Pacemaker therapy
Heart attack treatment.
Left anterior fascicular block is a cardiac condition which characterized by delay in transmission of impulse across the cardiac muscles, resulting in delayed pumping activity of the heart. This condition can be easily identified through an ECG. Also referred to as the left anterior hemiblock, this condition is brought about by a defect on the anterior half of the bundle of His, which comprises of special group of cells responsible for transmission of electrical impulse from the AV node to the apex of the heart. This condition is often associated and observed in acute cases of myocardial infarction.
