Adenosine is a medicine used in emergency settings to treat certain types of rapid, abnormal heart rhythms.
It is commonly used for:
• Supraventricular tachycardia: Used to quickly restore a normal heart rhythm during episodes of rapid heartbeat originating above the heart's ventricles.
• Diagnostic cardiac testing: Used during certain heart stress tests to help assess blood flow to the heart.
Flushing
Chest discomfort
Shortness of breath (dyspnea)
Headache
Dizziness
Adenosine works by briefly slowing the electrical signals passing through a specific part of the heart called the AV node.
This temporary slowing interrupts the abnormal electrical circuit responsible for a rapid heart rhythm, allowing the heart's normal rhythm to take over.
Because its effects last only a very short time, adenosine is given as a rapid injection under close medical monitoring, typically in a hospital setting.
