- Improve your confidence in using Adenosine effectively in clinical practice.
❓ Frequently Asked Questions
Q: What is Adenosine used for in emergency situations?
A: Adenosine is primarily used to treat supraventricular tachycardia (SVT) by slowing down electrical conduction in the heart and potentially converting the heart rhythm back to normal sinus rhythm.
Q: How is Adenosine administered?
A: Adenosine is administered as a rapid intravenous (IV) bolus followed by a saline flush. It’s crucial to administer it quickly due to its short half-life.
Q: What are the common side effects of Adenosine?
A: Common side effects include chest pain or pressure, shortness of breath, flushing, and brief periods of asystole (temporary pause in heart rhythm).
Q: What are the contraindications for Adenosine use?
A: Contraindications include second or third-degree AV block, sick sinus syndrome (unless a pacemaker is present), and known hypersensitivity to Adenosine.
Q: How does Adenosine work to stop SVT?
A: Adenosine acts on the AV node to slow down or temporarily block the electrical signals, disrupting the re-entrant circuit that causes SVT, thereby restoring a normal heart rhythm.
Q: What should I do if Adenosine doesn’t convert SVT?
A: If Adenosine fails to convert SVT, consider repeating the dose (as per protocol), other antiarrhythmic medications, or synchronized cardioversion.
