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 wave-front instead moves more quickly through the left anterior fascicle and right bundle branch, leading to a right axis deviation seen on the ECG. [2]
The American Heart Association has defined a LPFB as: [3]
The broad nature of the posterior bundle as well as its dual blood supply [4] makes isolated LPFB rare. [5]
