Left anterior fascicular block is a condition in which a blockage is present in one of the electrical branches that delivers electrical signals to a section of the heart's left ventricle. This cardiac condition is associated with scarring, or fibrosis, of the left ventricle, explains University of California San Francisco.
Study results reveal that a left anterior fascicular blockage may increase a person's chances of heart failure, atrial fibrillation or cardiac death, which are thought to be related to fibrosis of the left side of the heart, according to University of California San Francisco. Researchers hope that electrocardiogram tests may be used to detect the condition and predict serious cardiovascular diseases.
As of 2015 there are no known treatments for left anterior fascicular block, but there is therapy that may help individuals with the condition, claims University of California San Francisco. Therapy uses a pacemaker or cardiac resynchronization therapy. The pacemaker monitors the person’s heartbeat and detects abnormalities, states the National Heart, Lung, and Blood Institute. If abnormalities are detected, an electrical impulse is delivered to the heart.
Individuals can improve their cardiovascular health and decrease their risk of complications by leading a healthy lifestyle. This includes eating a healthy diet, engaging in regular exercise, and eliminating the use of tobacco, says University of California San Francisco.
