Adenosine


- indicated for PSVT
- if arrhythmias are not due to reentry involving the AV node or sinus node (eg, atrial flutter, atrial fibrillation, atrial or ventricular tachycardias), adeno
- sine will not terminate the arrhythmia but may produce transient AV or ventriculoatrial block that may clarify dx; 
- Dose: 
- half-life of adenosine is less than 5 seconds; 
- recommended initial dose is a 6-mg rapid bolus over 1 to 3 seconds 
- dose should be followed by a 20-mL saline flush; 
- if no response is observed within 1 to 2 minutes, a 12-mg repeat dose should be administered in the same manner
