Ver el código de «Trifascicular Block»

==Background==
*First degree AV block, right bundle branch block, and left anterior hemiblock 
*Conduction disease of all three fascicles: fight bundle branch, and left posterior and left anterior fascicles
*Trifascicular blocks can deteriorate into high grade blocks

==Clinical Features==
*ECG will show a bifascicular block and a prolonged PR interval
==Differential Diagnosis==
{{Heart block DDX}}

==Evaluation==

{{Heart block evaluation workup}}

===Diagnosis===
*Prolongation of the PR interval (first degree AV block) AND
**Right bundle branch block AND
**Either left anterior fascicular block or left posterior fascicular block

*'''ECG will show more atrial complexes than ventricular complex indicating high grade heart block'''
*'''Right budle branch block + extreme left axis deviation (left anterior fascicular block) + atrioventricular heart block'''

==Management==
{{Heart block management}}

==Disposition==
*Symptomatic patients should be admitted for monitoring and evaluation for a permanent pacemaker
*Cardiology consult
