2024年11月1日 · Regarding ACS patients, recent studies reinforce current guidelines in designating high risk ACS patients with RBBB for acute invasive evaluation, independent of ST-T deviations. However, in unselected ACS patients with RBBB, including self-presenters, further diagnostic measures like biomarkers and imaging should be initiated to rule in ACS ...

2017年12月12日 · What is a right bundle branch block (RBBB)? A RBBB is a block at the right bundle branch leading to delayed right ventricle depolarization. It can develop from various reasons (structural, function, iatrogenic), most commonly due to age, DM, and anterior wall infarctions (note – more perfusion from LAD though dual blood supply).

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 therapy. 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.

2009年11月1日 · Right bundle-branch block (RBBB) in the patient with acute coronary syndrome is a marker of significant potential cardiovascular risk; the RBBB pattern in the patient with acute coronary syndrome identifies a subgroup of patients with quite high short- …

Regarding ACS patients, recent studies support current guidelines that recommend acute invasive evaluation for high-risk ACS patients with RBBB, regardless of ST-T deviations. However, in an unselected group of ACS patients, differential diagnoses should also be investigated through additional diagnostic procedures.

2020年8月11日 · RBBB is a high risk feature in occlusion MI, especially if new and accompanied by LAFB. If a patient has ischemic symptoms and RBBB, compare with prior to see if this is new, and look for associated fascicular blocks and ST changes

Right bundle-branch block (RBBB) in the patient with acute coronary syndrome is a marker of significant potential cardiovascular risk; the RBBB pattern in the patient with acute coronary syndrome identifies a subgroup of patients with quite high short- …

In previous guidelines, acute coronary syndromes (ACS) with new or presumably new left bundle branch block (LBBB) were an indication for reperfusion treatment, preferably with primary angioplasty. Recent guidelines also included the presence of right bundle branch block (RBBB) in this recommendation.

2016年3月1日 · There was no significant interaction between RBBB and the type of ACS for either in-hospital or 6-month mortality (both p >0.50). In conclusion, across a spectrum of ACS, RBBB was associated with preexisting cardiovascular disease, high-risk clinical features, fewer cardiac interventions, and worse unadjusted outcomes.

The mystery of electrocardiographic findings of RBBB, borderline troponin levels, and atypical chest pain, especially in diabetics and the elderly patients, can be often solved by performing the screening ECHO to rule out the diagnosis of ACS.
