Adenosine is a medication used primarily to treat paroxysmal supraventricular tachycardia (PSVT), a type of fast heart rhythm that originates in the upper chambers of the heart.
How Adenosine Works:
Adenosine works by slowing down the electrical signals in the heart, which helps to restore a normal heart rhythm. It is administered intravenously (through a vein) and has a very short half-life, meaning it works quickly but also wears off quickly.
Other Uses:
Besides treating PSVT, adenosine may also be used for:
- Diagnosing heart conditions: Adenosine can be used to help doctors diagnose certain heart conditions, such as coronary artery disease.
- Research: Adenosine is also used in research to study the heart and other organs.
Important Considerations:
- Side effects: Adenosine can cause some side effects, such as chest pain, shortness of breath, and flushing. These side effects are usually mild and temporary.
- Contraindications: Adenosine should not be used in people with certain medical conditions, such as asthma, severe heart block, or low blood pressure.
