WebFeb 11, 2024 · Abstract. Ventricular tachycardias originating from the Purkinje system are the most common type of idiopathic left ventricular tachycardia. The majority if not all of the reentrant circuit involved in this type of tachycardia is formed by the Purkinje fibres of the left bundle branch, particularly the left posterior fascicle. WebWhat are fascicles? When a group of muscle fibers is “bundled” as a unit within the whole muscle it is called a fascicle. Fascicles are covered by a layer of connective tissue called perimysium (see Figure 10.3). Fascicle arrangement is correlated to the force generated by a muscle and affects the muscle's range of motion. cell phone covers for zte avid 579
