QRS duration of > 120 milliseconds rsR' "bunny ear" pattern in precordial leads Slurred S waves in leads I, V5, and V6. Remember that T wave inversions and ST segment depression is normal in leads V1 ...

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.

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 ...

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 ...

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 ...

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

The diagnosis is NSR, first-degree AV block, 3:1 AV block, Mobitz type II, and high-degree AV block. The rhythm is regular with a rate of 30 beats/min. The QRS complex duration is normal (0.08 sec) ...

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 ...
