A right bundle branch block (RBBB) involves a delay in the electrical impulses reaching the heart’s right ventricle, which can affect the heart’s ability to pump blood effectively. While RBBB doesn’t ...

Impulses, or electrical signals, travel through both the left and right chambers of your heart to make it pump. But if the pathway is blocked, the impulses may move slower than normal or irregularly.

Q: I recently had an ECG that showed that I have a "left bundle branch block." What does this mean? A: When your heart beats, it does so in response to electrical signals. Your heart muscle is ...

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 ...

Your heart isn’t plugged into an outlet. And you don’t use a switch to turn it on. But just like a lamp, your heart runs on an electrical system. Every time your heart beats, an electrical signal ...

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 ...

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 ...

The health concern: An abnormality in the cardiac electrical system known as a bundle branch block. Why it's in the news: It's not, actually. This topic actually came to me from a concerned colleague ...

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 ...
