Mechanism		Delay atrioventricular conduction				Delay atrioventricular conduction
Key Mechanism Factor 1
		Factor Name		Atrioventricular block
		Factor Description		Atrioventricular block is a type of cardiac conduction block that occurs when the electrical signal from the atria to the ventricles is impaired. In an Atrioventricular block, this electrical signal is either delayed or completely blocked. When the signal is completely blocked, the ventricles produce their own electrical signal to control the heart rate. The heart rate produced by the ventricles is much slower than that produced by the sinus node.
Mechanism Description		Increased risk of atrioventricular block by the combination of Betaxolol (ophthalmic) and Pilocarpine

Recommended Action
Management		If these drugs must be given together, consider the possibility for arrhythmias and administer with caution. Patients should be advised to notify their physician if they experience irregular or slow heartbeats, palpitations, or syncope.
