What is the classification?
Antiarrhythmic
What are the actions?
• Transiently blocks conduction through the AV node
• Interrupts reentry pathways through the AV node
What are the indications?
• Stable SVT (Supraventricular tachycardia, AVNRT atrioventricular nodal reentry tachycardia)
• Consider while preparations are made prior to cardioversion
What are the contraindications?
• Allergy to the drug
• Heart block
• Drug-induced tachycardia (e.g. from cocaine)
• Atrial flutter and atrial fibrillation
What are the precautions?
Very short duration of action; must reach the heart within 10-20 seconds
What are the common concentrations?
• 6mg/2mL prefilled syringe, 6mg/2ml vial
• 12mg/4ml prefilled syringe, 12mg/4ml vial
What is the adult dosage?
• 1st Dose: 0.1 mg/kg rapid IV push (maximum dose 6 mg) with 5-10 mL flush
•2nd Dose: .02 mg/kg rapid IVP (maximum dose 12 mg) with 5-10 mL flush
What is the pediatric dosage?
•1st Dose: 0.1 mg/kg rapid IV push (maximum dose 6 mg) with 5-10 mL flush
•2nd Dose: 0.2 mg/kg rapid IVP (maximum dose 12 mg) with 5-10 mL flush
What are the side effects?
• Headache
• Facial flushing
• Chest pressure
• Nausea
What are the key points?
• Half life less than 10 seconds
• Consider diluting small medication volume of pediatric dosages with 5 mL normal saline, followed by 5-10 mL flush
• Continuous ECG and attempt to capture conversion on ECG paper
• Vital signs before and within 5 minutes after administration
• Position patient supine, consider elevation of legs
What is the protocol use?
Narrow complex tachycardia
