Patient's Query

Hello doctor,

I am wondering if there is any specific thing to look for on an EKG to show a bifascicular block. I am trying to learn EKG reading and was wondering if you can help me.

Hi,

Welcome to icliniq.com.

Look for the right bundle branch block and axis deviation. If the left anterior or posterior hemiblock is also present, this makes it bifascicular block. If AV block (atrioventricular block) also, this makes trifascicular block. If the left anterior and posterior blocks combine, it is called a left bundle branch block, if left and right both bundles block, this is called a complete heart block and third-degree AV block. If you are a medical personnel, it is easy to understand, if layman, then it may take some time to get used to EKG (electrocardiogram).

Same symptoms don't mean you have the same problem. Consult a doctor now!
