There were no symptoms associated with the tachycardia. A 12-lead ECG was recorded (Fig. I). The tachycardia terminated after infusion of 12 mg of adenosine (Fig. 2). What is the mechanism of this adenosineresponsive wide QRS complex tachycardia?
Misdiagnosis of wide complex tachycardias is still a common clinical problem. Because the electrophysiologic spectrum of action of adenosine is well characterized (Table 102-3), adenosine infusions for diagnostic purposes are potentially helpful.2122 Limitations to this proposed usage include the risk fo...

Since it induces conduction block in the AV node, adenosine has diagnostic utility in patients with narrow QRS complex tachycardia. Similarly, adenosine could be of the most value in hemodynamically stable wide QRS tachycardia (WQRST) with 1:1 VA conduction when there is difficulty in ...
Adenosine has received wide acceptance as the drug of choice for initial treatment of supraventricular tachycardias (supraventricular tachycardia), and as a diagnostic adjunct in hemodynamically stable, wide-complex tachycardias.
