本综述深入探讨了永久性心房颤动（AF）患者中束支传导阻滞（BBB）和电轴偏倚（AD）的共存现象及临床关联。研究通过回顾性分析揭示AF与左束支传导阻滞（LBBB）显著相关，而窦性心律（SR）则与左电轴偏倚（LAD）密切关联。年龄分层显示年轻AF患者更易并发LBBB ...

Global LV systolic function was accessed by fractional shortening, ejection fraction, and cardiac output. Regional LV wall motion was assessed based on motion and thickening of individual LV wall ...

本研究针对传统心电图(ECG)分析依赖人工判读、效率低且易受主观因素影响的问题，提出了一种基于脉冲神经网络(SNN)的仿生计算方法。通过将ECG信号转换为脉冲序列，结合漏积分发放(LIF)神经元和脉冲时序依赖可塑性(STDP)机制，实现了对心房颤动(AFIB)、束支传导 ...

Left bundle branch block (LBBB) is a type heart block. It results from a problem with the electrical conduction system that enables the heart to beat. It may cause no symptoms, but an ...

Yogesh N. Reddy, MBBS: Hi. This is Yogesh Reddy, cardiology fellow at Mayo Clinic. Today we will be discussing the very common clinical scenario of a left bundle branch block (LBBB) on ...

August 4, 2004 — In an era when the number of candidates for implantable cardioverter defibrillator (ICD) therapy continues to grow, identifying specific patients at risk for arrhythmic death -- the ...

The ECG shows normal sinus rhythm at 75 beats per minute with a prolonged PR interval of 0.24 sec, ie, first-degree atrioventricular block. The QRS duration is about 0.16 sec with a left bundle branch ...

Enlarge Source: Learn the Heart Which of the following does the above ECG represent? The ECG shows sinus tachycardia at about 110 beats per minute with a prolonged PR of 0.22 seconds: first-degree ...

LBBB is linked to electrical abnormalities, causing inefficient heart pumping, dilation, and systolic dysfunction. The study found LBBB associated with increased heart failure risk, surpassing other ...

DEAR DOCTOR K: I recently had an ECG that showed that I have a "left bundle branch block." What does this mean? DEAR READER: When your heart beats, it does so in response to electrical signals. Your ...
