How It Works
Adenosine reduces the normal flow of the electrical impulses through the atrioventricular (AV) node of the heart.
Why It Is Used
Adenosine is used to restore a normal heart rate and rhythm when you are having an episode of supraventricular tachycardia.
How Well It Works
Adenosine can be very effective at slowing or ending a rapid heart rate if the problem is caused by an abnormal electrical pathway in the heart. Adenosine will not work if the fast heart rate has a different cause. Therefore, it may have limited value in diagnosing tachycardia or helping identify the location of the fast heart rate.
Side Effects
Adenosine is always given by a health professional while you are hooked up to a heart monitor. It is given through a vein (intravenous, or IV). Adenosine works very quickly and lasts only a short period of time (less than 1 minute). Side effects may include:
- Lightheadedness and dizziness.
- Blurred vision.
- Shortness of breath.
- Facial flushing.
- Metallic taste.
- Anxiety.
- Chest pressure.
- Brief loss of consciousness.
See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)
What To Think About
Adenosine is a quick-acting, short-term therapy intended to convert the fast heart rhythm of a supraventricular tachycardia (SVT) that affects the AV node back to a normal rate. Adenosine cannot be used for atrial fibrillation associated with Wolff-Parkinson-White syndrome. In atrial fibrillation and atrial flutter, adenosine's effect is only very short-lived.
