【佳学基因检测】左束支阻滞基因检测Left Bundle Branch Block 遗传性疾病的基因检测导读: 左束支传导阻滞 (LBBB) 是一种常见的心电图 (ECG) 异常,见于希-浦肯野系统左前束和后束的正常心脏传导受损的患者。虽然左束支传导阻滞(LBBB)通常与严重的心脏病相关,并且通常是心肌损伤、劳损或肥大的结果,但也可见于没...
ECGelectroanatomical mappingleft bundle branch blockresynchronization therapyBackground The presence and extent of ventricular dyssynchrony are currently assessed from the QRS complex morphology and width. However, similar electrocardiography (ECG) pattern may be caused by variable ventricular activation ...

left bundle branch blockintraventricular blockLBBB Electrocardiographic disorder characterized by intracardiac conduction block in the left bundle branch, below the level of the His bundle, which arises in the setting of a variety of inherited......
It is common knowledge that the ECG diagnosis of completed myocardial infarction in the presence of left bundle-branch block (LBBB) is extremely difficult and often impossible. More than 50 rules have been proposed as criteria for interpreting Q-wave equivalents superimposed on the QRS complex in ...
in addition, all of the left bundle branch block beats in record 214 were originally labelled as normal beats. 此外,记录214中所有左束支阻滞心拍起初是标记为正常心拍。 hi.baidu.com 6. Study of diagnostic value of ECG-gated myocardial perfusion imaging in left bundle branch block with coronary...
QuestionHow does the performance of a new left bundle branch block (LBBB) criterion developed based on intracardiac recordings of patients compare with that of current strict criteria? FindingsIn this diagnostic study of 75 patients, LBBB pattern on surface electrocardiography (EC...
Painful left bundle branch block (LBBB) is a rarely diagnosed chest pain syndrome caused by intermittent LBBB in the absence of myocardial ischemia. Its prevalence, mechanism, detailed electrocardiographic (ECG) features, and effective treatments are not well described. Objectives The purpose of this ...
