Adrenaline Versus Atropine for AVNRT Induction

AVNRT is the most frequent form of paroxysmal supraventricular tachycardia. In French the term is TRIN (tachycardie par reentre intra-nodale) and in English AVNRT (atrioventricular node reentrant tachycardia). It can be induced in the EP lab by atrial or ventricular stimulation in the basal state or after drug administration. The drug of choice is isoprenaline, but in some European countries, the lack of the drug produced efforts to search for another options. There is no study that compares efficacy of atropine versus adrenaline for AVNRT induction in the EP lab. In our study, we compared the two drugs in terms of efficacy and side effects. The investigators hypothesized that adrenaline would be a better and more convenient for the induction of arrhythmias since adrenaline is administered as an intravenous infusion over several minutes, in comparison to atropine, which is administered as a bolus. We demonstrated our hypothesis by statistical analysis.
