Abstract

The successful treatment of paroxysmal supraventricular tachycardia with adenosine 5` triphosphate (ATP) was initially reported by Somlo1 in 1955. Sharma et al2 noted the value of intravenous ATP in the diagnosis and management of wide QRS complex tachycardia. ATP in incremental doses has been used for the non-invasive diagnosis of concealed accessory pathways3. Non-invasive diagnosis of dual AV node physiology (DAVNP) in patients with AV nodal reentrant tachycardia by administration of ATP or adenosine has been reported by different authors4,5. Though many of the studies were using incremental dosage, single dose tests with ATP6 and adenosine7 have also been useful in the diagnosis of DAVNP. The test is useful in sinus rhythm to establish the presence of DAVNP. DAVNP is considered to be present when at least one of the following events occur following ATP injection: 1) PR interval increases or decreases by >50 ms in 2 consecutive sinus beats; 2) an AV nodal echo beat is observed; 3) AVNRT develops. In this issue of the Journal, Belhassen et al8 report that DAVNP is present in a relatively high proportion (36.5%) of patients following termination of AVNRT with ATP but is much less frequent (5.5%) in control patients. In addition, they show that the occurrence of DAVNP following the administration of ATP in sinus rhythm is a good predictor of its occurrence after termination of AVNRT with ATP. Thus, findings at termination of tachycardia by ATP may be useful in the noninvasive diagnosis of the mechanism of a paroxysmal supraventricular tachycardia.
