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 …

2018年7月2日 · Sinus tachycardia and RBBB are clearly common ECG findings with acute PE — but they are not specific for this diagnosis. Without availability of a prior tracing — we have no …

2024年10月5日 · RAD has three major causes [1] Lateral Q-wave MI. [2] RVH and/or PE. [3] LPFB: r S in Lead I (wave with considerable negativity). qR in III and aVF. rS in Lead I and qR …

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 …

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 …

Along with STE-aVR, STE in V1 with RBBB represents an ischemic lesion in the basal septal area, often coupled with deficient backup circulation to the basal right septum from the conus …

2024年7月26日 · There is a first-degree AV block, with a PR interval of 232 ms. We see the right bundle branch block (RBBB) pattern: rSR’ in the right precordial leads (with a tiny q wave in …

2018年2月8日 · Admittedly, the presence of RBBB clearly makes recognition of ischemic change more challenging — but the presence of these diffuse ST-T wave abnormalities with ST …

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. …

Why is this a right bundle branch block? We see a SR with broad QRS complexes (more than 120 ms). These are positive in the rightward leads III and especially in V1 and V2. In the more …
