A member asked:

What does sr. left anterior fascicular block mean?

A doctor has provided 1 answer

Conduction system pr: Part of the conduction system of the heart doesn't work. If more fascicles are blocked, you are at risk of needing a pacemaker. More important is the cause. Is there a blocked artery or weak heart muscle (aka cardiomyopathy?) generally these won't be a problem as long as you know why you have it. You should see a doctor.
