Adenosine/Adenocard Antidysrhythmic agent. Slows conduction time through the AV node, interrupts AV
node pathways to restore NSR. Converts supraventricular tachycardia (SVT) to
sinus rhythm. Rapid IV (1-2 seconds) push, flush immediately with normal saline.
6mg/6mg/12mg Dosed: 12mg/4ml
Adenosine (Adenocard) Slows the conduction time through the A-V node, can interrupt the reentry
pathways through the A-V node and can restore normal sinus rhythm in patients
Actions: with PSVT, including PSVT associated with WPW.
Adenosine (Adenocard) Flushing, Chest Pain, brief periods of Asystole, Bradycardia, Ventricular Ectopy.
Adverse Effects:
