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.

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 ...

Q: I recently had an electrocardiogram as part of a routine physical exam. The report said I had a bundle branch block. What does that mean? Will I need a pacemaker? A: Bundle branch blocks are ...

Q-I`m a 27-year-old female in good health. However a recent EKG turned up a ”bundle branch blockage.” The doctor says it is an interruption in the heart`s electromagnetic field. What else can you tell ...

DEAR DR. DONOHUE You were asked about a right bundle branch block and you said "Electric current still makes its way to the right ventricle. This doesn't mean you are on the verge of dying." A few ...

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 ...

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 ...

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 ...
