- Brand Name: Adenocard, Adenoscan
- Class: Antiarrhythmic
- Indication: Supraventricular tachycardia (SVT), Paroxysmal SVT
- Quick-acting, short-term therapy used to restore a normal heart rate and rhythm when there is SVT present
- Always given when hooked up to EKG
- Given intravenously (IV)
- May be used to diagnose tachycardia
- Will slow the heart rate when it is due to abnormal electrical pathway in the heart; will not work if the fast heart rate is due to other cause
- May slow heart rate for a short time if you also have atrial fibrillation or atrial flutter
- Side Effects:
- Skin flushing in the face
- Shortness of breath
- Headache
- Nausea
- Chest pain or pressure
Supraventricular Tachycardia:
- Supraventricular tachycardia (SVT): a fast heart rate that begins in the upper part of the heart (atria), above the ventricles
- Normally, the heart's electrical system precisely controls the heart's rhythm; in this condition, abnormal electrical connections cause the heart to beat too fast.
- Most supraventricular tachycardias result from abnormal electrical connections (bypass tracts) in the heart that short-circuit the normal electrical system and cause an increase in electrical activity.
- Supraventricular tachycardia may cause an uncomfortable feeling that the heart is racing, pounding, and/or beating irregularly (palpitations). Additional symptoms include feeling dizzy or lightheaded, near-fainting or fainting (syncope), shortness of breath, chest pain, throat tightness, and sweating.
- Some supraventricular tachycardias do not cause symptoms and may not need treatment. But if supraventricular tachycardia recurs, medicines or a procedure called catheter ablation may be needed to correct the abnormal heartbeat.
Catheter Ablation:
- Catheter ablation (ab-LA-shun) is a medical procedure used to treat some types of arrhythmia (ah-RITH-me-ah). An arrhythmia is a problem with the rate or rhythm of the heartbeat.
- During catheter ablation, a series of catheters (thin, flexible wires) are put into a blood vessel in your arm, groin (upper thigh), or neck. The wires are guided into your heart through the blood vessel.
- A special machine sends energy to your heart through one of the catheters. The energy destroys small areas of heart tissue where abnormal heartbeats may cause an arrhythmia to start.
- Catheter ablation often involves radiofrequency (RF) energy. This type of energy uses radio waves to produce heat that destroys the heart tissue. Studies have shown that RF energy works well and is safe.
