This is a first-degree AV block. There is no action necessary for this dysrhythmia. This is not a life-threatening dysrhythmia. Defibrillation is not necessary. The healthcare provider does not need to be notified. Sublingual nitroglycerin is used for chest pain.
Answer to Question 2
Correct Answer: 1, 2, 3, 5
Calcium channel blockers decrease automaticity and AV nodal conduction. They are used to manage supraventricular tachycardia. These medications include amlodipine (Norvasc), verapamil (Calan), and diltiazem (Cardizem). Adenosine (Adenocard) decreases conduction through the AV node and is used to treat supraventricular tachycardia. Propafenone (Rythmol) is used to reduce or eliminate tachydysthymias associated with reentry.
