Transesophageal Cardioversion and Defibrillation

The sensitivity of transesophageal pacing for screening in atrial tachycardias.

Kesek M, Sheikh H, Bastani H, Blomstrom P, Lundqvist CB. Department of Cardiology, Akademiska Hospital, Uppsala University, Sweden. Int J Cardiol 72(3):239-42, 2000. Transesophageal atrial pacing and recording performed in 128 patients for palpitations or tachycardia was retrospectively evaluated and compared to the same procedure in 77 routinely evaluated patients after a catheter ablation procedure. The sensitivity and specificity of the described protocol was 74 and 90% respectively. The procedure was well tolerated and a majority of patients could be completely evaluated according to the protocol. The outcome of the first time investigation influenced the subsequent choice of therapy in the studied population. The results suggest that transesophageal pacing is a valuable tool for evaluation of atrial tachycardias with specificity, sensitivity and tolerability comparable to other noninvasive methods used in cardiology.
