Answer:
by Texas Heart Institute cardiologist, Abdi Rasekh, MD
This is a minor ECG abnormality without consequence and no need for therapy. Electrical activity travels from upper chamber to lower chamber through electrical pathways called right bundle and left bundle. The left bundle bifurcates [divides and proceeds] to anterior and posterior fascicles. A delay in electrical conduction of anterior fascicle is called left anterior hemiblock.
