2022年6月11日 · Bundle branch block is a condition in which there's a delay or blockage along the pathway that electrical impulses travel to make the heart beat. It sometimes makes it harder for the heart to pump blood to the rest of the body.

A bundle branch block (BBB) is a blockage or disruption to the electrical signal that causes your heart to beat. BBB can affect your right ventricle (right bundle branch block), left ventricle (left bundle branch block) or both ventricles.

2024年10月8日 · Left bundle branch block (LBBB): 1) rS complex in V1 (tiny R wave, deep S wave) 2) Characteristic lateral lead morphology in V5-6 3) Note appropriate discordance in V1 with ST elevation and upright T wave

A bundle branch block can be diagnosed when the duration of the QRS complex on the ECG exceeds 120 ms. A right bundle branch block typically causes prolongation of the last part of the QRS complex and may shift the heart's electrical axis slightly to the right.

2022年6月11日 · If you have a left bundle branch block, you will need a thorough medical exam. Tests that can be used to diagnose a bundle branch block or its causes include: Electrocardiogram (ECG or EKG).

Left bundle branch block (LBBB) occurs when something blocks or disrupts the electrical impulse that causes your heart to beat. This block leads to an abnormal heart rhythm. A diagnosis of left bundle branch block often means that you have an underlying heart condition.

2023年9月4日 · 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...

A bundle branch block refers to a condition that arises from a blocked electrical pathway in the heart, causing the left and right sides of your heart to beat out of sync. When a person has a “right” bundle branch block, the right side of the heart beats slightly later than the left side.

2022年7月23日 · This article will focus on the physiology, pathophysiology, and clinical consequences of damage to the bundle branches, including left bundle branch block (LBBB) and right bundle branch block (RBBB).

Bundle branch block is partial or complete interruption of impulse conduction in a bundle branch; fascicular block is similar interruption in a hemifascicle of the left bundle. The disorders often coexist. There are usually no symptoms, but presence of either suggests a heart disorder.
