What is left anterior branch conduction block?

Left anterior branch conduction block is a disease caused by myocarditis, coronary atherosclerotic heart disease and other factors, resulting in damage to the left anterior branch of the heart, resulting in nerve conduction block.

Cardiac rhythm is formed by nerve impulses emitted by the sinus node and transmitted to the internodal bundle and atrioventricular node in turn. If the patient has heart disease or electrolyte disorder, hypertension, hyperlipidemia and other systemic diseases, resulting in damage to the left anterior branch of the heart, it can cause left anterior branch conduction block.

Simple left anterior branch conduction block generally has no obvious clinical symptoms. If there is no organic heart disease, timely clinical treatment usually has a better prognosis.
