2021年12月9日 · In LPFB, impulses are conducted to the left ventricle (LV) via the anterior fascicle, which inserts into the upper, lateral wall of the LV along its endocardial surface. Depolarisation spreads from endocardium to epicardium and thus the initial vector is directed upwards and leftwards, towards lateral leads.

2022年6月14日 · Left posterior fascicular block is an obstruction in the transmission of electrical impulses in the left ventricle of your heart. This leads to an abnormal heartbeat. Most often, it’s caused by coronary artery disease or another heart condition. When it occurs with a block in your right ventricle, it can be serious.

Learn about left anterior fascicular block (hemiblock) and left posterior fascicular block, with emphasis on ECG criteria, causes, effects and management.

Left posterior fascicular block (LPFB), a pattern (formerly called left posterior hemiblock) seen on the surface electrocardiogram (ECG), results when normal electrical activity in the His-Purkinje system is delayed or interrupted.

Left posterior fascicular block (LPFB) is an intraventricular conduction disturbance of the left posterior fascicle (LPF) of the left bundle branch (LBB), which travels to the inferior and posterior region of the left ventricle (LV), the left ventricle inflow tract (LVIT).

A left posterior fascicular block (LPFB) also known as a left posterior hemiblock (LPHB) occurs when the posterior fascicle of the left bundle branch is no longer able to conduct...

A left posterior fascicular block (LPFB), also known as left posterior hemiblock (LPH), is a condition where the left posterior fascicle, which travels to the inferior and posterior portion of the left ventricle, [1] does not conduct the electrical impulses from the atrioventricular node.

The left Posterior Fascicular block (Lpfb) is defined by irregular contraction of heart muscles, whereby it travels to the inferior and posterior portion of the left ventricle of the heart and does not conduct electrical impulse transmission from the atrioventricular node.

2018年11月1日 · Left posterior fascicular block (LPFB) is an intraventricular conduction disturbance of the left posterior fascicle (LPF) of the left bundle branch (LBB), which travels to the inferior and posterior region of the left ventricle (LV), the left ventricle inflow tract (LVIT).

左后分支阻滞常见的病因有冠心病，在 心肌梗死 时的发生率为1%左右，因为需多支血管堵塞导致前壁合并下壁及右心室梗死，或前降支病变导致室间隔广泛缺血、坏死时才可能出现，并且极少单独出现。 其他尚有 高血压 病、心 肌病 、 心肌炎 、主动脉瓣病变或室内传导系统退行性变、夹层 动脉瘤 、急性肺心病、 主动脉弓缩窄 、高血钾等。 也可见于健康人。 左后分支阻滞本身无明显症状，如其合并右束支阻滞，则会出现晕厥，抽搐等。
