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.

2020年9月14日 · RBBB is caused by diseases that affect the right bundle branch or the myocardial region, where the right bundle branch is located. Possible causes include trauma, structural changes, infiltrative diseases (eg, sarcoidosis), myocarditis, and myocardial infarction.

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 …

2024年10月8日 · There is increasing literature suggesting that in the context of chest pain, a new RBBB is highly concerning for OMI and a potential indication for immediate reperfusion …

Objectives: This study aims to examine the right and left ventricular systolic functions in patients with idiopathic RBBB and compare them to those in a healthy control group. Material and methods: Echocardiographic images were obtained from patients with idiopathic RBBB and healthy control participants.

2024年10月5日 · RBBB doesn't affect the net QRS axis, although it does produce some terminal right-axis deviation. When determining the axis focus on the initial 60-80 ms (ignore the terminal, low-voltage components at the end of the QRS complex).

2025年1月28日 · Echocardiographic images were obtained from patients with idiopathic RBBB and healthy control participants. Conventional echocardiographic parameters were measured. Two-dimensional (2D) speckle tracking strain analysis was used to assess deformation indices.

A growing body of evidence suggests that the presence of a right bundle branch block (RBBB) is a negative prognostic indicator in patients with and without preexisting heart disease.

2019年6月21日 · Right bundle branch block may indicate pathology in the right side of the heart e.g. right ventricular strain (especially due to pulmonary embolism). Right bundle branch block …

2020年1月8日 · A clinical review of right bundle branch block (RBBB) with emphasis on ECG (EKG) criteria, symptoms, causes, management and interpretation of ischemia / infarction.
