2024年10月8日 · The right bundle branch is supplied by LAD perforators in most patient populations and thus occlusion of this branch may manifest as a new RBBB +/- LAFB. ECG Examples of Right Bundle Branch Block Example 1

In right bundle branch block (RBBB), the right ventricle depolarizes after the left ventricle, allowing its electrical vectors to become evident. These vectors manifest in the later part of the QRS complex as an R’ wave (pronounced “R prime”), which is directed anteriorly and rightward.

Below is an ECG displaying a right bundle branch block with an anterior ST segment elevation MI, followed by some other examples. Some variations of right bundle branch blocks can occur....

Right bundle branch block is a problem with your right bundle branch that keeps your heart’s electrical signal from moving at the same time as the left bundle branch. Instead of moving together on the left and right sides, the signal on the right side is running behind. This creates an irregular heartbeat. Usually, the problem isn’t serious.

2023年8月8日 · Right bundle branch block (RBBB) is an electrocardiogram finding that occurs when the physiologic electrical conduction system of the heart, specifically in the His-Purkinje system, is altered or interrupted resulting in a widened QRS …

⚠️ (RBBB + LVH) or (RBBB + BER) may create patterns that are impossible to diagnose on a single ECG. In the presence of unusually high voltages, STE may be less specific for ischemia. ⚠️ (RBBB plus diffuse subendocardial ischemia) may create dramatic ST depression in V1-V3 that mimics a posterior MI.

2022年7月23日 · An overview of left and right bundle branch block (BBB) including pathophysiology and how to identify BBC on an ECG using WiLliaM and MarRoW.

RBBB, a pattern seen on the 12-lead ECG, results when normal electrical activity in the His-Purkinje system is interrupted for some reason. The normal sequence of activation is altered in RBBB, with a resultant characteristic appearance on the ECG manifest by a widened QRS complex and changes in the directional vectors of the R and S waves.

2024年7月26日 · The ECG shows normal sinus rhythm and right bundle branch block. The ECG criteria for right bundle branch block are: 1) QRS wide at 120 ms or more (.12 sec. or more). 2) Supraventricular rhythm. 3) Terminal waves indicating that the right ventricle is depolarizing late. Because the right bundle branch is blocked, the left ventricle depolarizes ...
