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), adenosine 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 … Read more
