For the past few years, a new method for the investigation and treatment of arrhythmias has been used: transoesophageal atrial pacing and recording (TAPR). In the light of 6 cases observed recently, we review the technical aspects and the indications for TAPR. A bipolar stimulation catheter is inserted in the oesophagus and positioned in the area where the atrial wave of greater amplitude is recorded. Atrial stimulation is done with impulses of long duration obtained with a special stimulator. Two cases validated this technique which was effective to correct atrial flutter in a neonate with heart failure resistant to medical treatment as well as in a 5 year-old child. The value of TAPR as a diagnostic tool in cases of tachycardia is discussed in the context of 2 cases: a 5 week-old with wide QRS and a 14 month-old with narrow QRS. Finally, the value of TAPR for monitoring the efficacy of anti-arrhythmia medications is illustrated by 4 cases of supraventricular tachycardia, in whom the optimal dosage of the anti-arrhythmic drug used was determined with the help of TAPR-induced tachycardia. The current literature concerning the technique, indications and results of TAPR are reviewed. This method is likely to take a great importance for the study and treatment of supraventricular arrhythmias in children.
