Left posterior fascicular block
Classification and external resources
ICD-10	I44.5

A left posterior fascicular block (LPFB) is a condition where the left posterior fascicle, which travels to the inferior and posterior portion of the left ventricle, 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.

The American Heart Association has defined a LPFB as:

• Frontal plane axis between 90° and 180° in adults
• rS pattern in leads I and aVL
• qR pattern in leads III and aVF
• QRS duration less than 120 ms

The broad nature of the posterior bundle as well as its dual blood supply makes isolated LPFB rare.

• Left bundle branch block
• Left anterior fascicular block
