   Third Degree AV Block Treatment Options Third-degree heart block, also known as AV dissociation, has no communication from the atria to the ventricles; it is typically treated in the field only if the resultant bradycardia is so severe that the patient is hypotensive and displaying signs of altered mental status. At that point, the best option is TCP because atropine will serve only to accelerate the P rate, leaving the ventricular R rate unchanged.
