2024年10月8日 · New LBBB in the context of chest pain was once considered a “STEMI-equivalent” and part of the criteria for thrombolysis. However, more up-to-date data suggests that chest pain patients with new LBBB have little increased risk of acute myocardial infarction at the time of presentation.

2024年10月5日 · New-onset LBBB, especially in the context of acute coronary syndromes, is considered an ST-segment elevation equivalent, indicating a potential risk of myocardial infarction. LBBB is also linked to an increased likelihood of developing heart failure and arrhythmias, such as atrial fibrillation or ventricular tachycardia.

2024年3月28日 · In patients with significant LV dysfunction, LBBB results in left ventricular dyssynchrony and may contribute to heart failure (HF). The anatomy, clinical manifestations, differential diagnosis, prognostic implications, and treatment of LBBB will be reviewed here.

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.

2017年2月28日 · When a new LBBB is caused by MI, the infarction site is usually anterior or anteroseptal, and the MI usually involves a large territory of myocardium. Most cases of LBBB in suspected MI are therefore not a result of focal infarction.

2021年9月13日 · It is conceivable that patients with underlying left bundle‐branch block (LBBB) can present with AMI with either STEMI equivalent (acute occlusion of an epicardial artery) or NSTEMI equivalent physiology.

Learn about left bundle branch block (LBBB), with emphasis on ECG criteria, differential diagnoses, causes, management and diagnosis of ischemia/infarction.

Episodic (transient/ intermittent) left bundle branch block (LBBB) has been associated with different conditions such as bradycardia, tachycardia, anesthesia, acute pulmonary embolism, changes in intrathoracic pressure, chest trauma, cardiac interventional procedures, mad honey poisoning, and in other clinical settings.

2025年2月27日 · ST-segment changes may be observed in other conditions including acute pericarditis, left ventricular hypertrophy, LBBB, Brugada syndrome, right ventricular pacing, Takotsubo syndrome, and early repolarization that may obscure the diagnosis of STEMI. 12 New or presumably new LBBB at presentation occurs infrequently and should not be considered ...

Patients with a suspected acute coronary syndrome (ACS) and left bundle branch block (LBBB) present a unique diagnostic and therapeutic challenge to the clinician. Although current guidelines recommend that patients with new or presumed new LBBB ...
