Adenosine

Adenocard (adenosine injection) slows conduction time through the A-V node, can interrupt the re-entry pathways through the A-V node, and can restore normal sinus rhythm in patients with paroxysmal supraventricular tachycardia (PSVT), including PSVT associated with Wolff-Parkinson-White Syndrome.It has a possible role in the first-line treatment of unstable SVT and is generally safe and effective when used to treat and/or diagnose wide complex tachycardias. There is a small risk of inducing serious arrhythmias, such as prolonged atrioventricular blockade and ventricular fibrillation.

Dosage

Initial dose: 6 mg given as a rapid intravenous bolus (administered over a 1 to 2 second period). Repeat administration: If the first dose does not result in elimination of the supraventricular tachycardia within 1 to 2 minutes, 12 mg should be given as a rapid intravenous bolus .

Contraindication

• Third Digree Heart Block

• In drug or poison induced Tachycardia
