Question

When administering the drug adenosine to a patient with supraventricular tachycardia (SVT), the nurse is to push it rapidly followed by a rapid flush. When watching the patient’s rhythm, the nurse sees the patient go into asystole then into a regular rhythm. What is the reason for this change in rhythm?

Answer 1

ANSWER.

* Adenosin is an antiarrythmic agent used in supraventricular tachycardia.

* Adenosin act by slowing the rate of impulse transmission through AV nodes

   thereby decreasing the heart rate.

* This sudden change in conduction of impulse through AV node due to the effect

   of adenosin result in asystole for few seconds then change into a regular rhythm.
