[Adenosine-sensitive atrial tachycardia]

The authors describe a case of a 71 year old man who suffered from chronic lung disease and had atrial tachycardias. 18 mg adenosine terminated his paroxysmal supraventricular tachycardia. The Holter monitoring showed that the tachycardia began at the late diastole with normal PQ interval, suggesting that an ectopic atrial tachycardia was terminated. They propose that adenosine is a "new" drug for termination of some form of atrial tachycardia.
