Remember that T wave inversions and ST segment depression are normal in leads V1 to V3 in the presence of a right bundle branch block; thus, myocardial ischemia technically cannot be easily determined ...

A bundle branch block is characterized by a delay or an obstruction to the electrical impulses that prompt the heart to beat. These blockages along the heart’s electrical pathway can occur in healthy ...

Yogesh N. Reddy, MBBS: Hi. This is Yogesh Reddy, cardiology fellow at Mayo Clinic. Today we will be discussing the very common clinical scenario of a left bundle branch block (LBBB) on ...

A person with RBBB typically does not have symptoms and may not know they have the condition. On rare occasions, a person may faint due to a severe block, though this is unlikely to occur unless other ...

Left bundle branch block (LBBB) is a type heart block. It results from a problem with the electrical conduction system that enables the heart to beat. It may cause no symptoms, but an ...

QRS duration greater than 120 milliseconds Absence of Q wave in leads I, V5 and V6 Monomorphic R wave in I, V5 and V6 ST and T wave displacement opposite to the major deflection of the QRS complex A ...

LBBB is linked to electrical abnormalities, causing inefficient heart pumping, dilation, and systolic dysfunction. The study found LBBB associated with increased heart failure risk, surpassing other ...

Almost one-third of patients undergoing transcatheter aortic valve replacement (TAVR) with a balloon-expandable device develop new-onset left bundle branch block, although the condition resolves by ...

Dear Dr. Roach: I am a 63-year-old male who, during a routine EKG, showed a left bundle branch block. Can you tell me anything about this diagnosis, what it means, any treatment, future concerns, etc.
