[Transesophageal supra-burst pacing to terminate paroxysmal supraventricular tachycardia].
A new cardiac stimulation mode (transesophageal supra-burst pacing) to terminate paroxysmal supraventricular tachycardia (PSVT) in the clinical and electrophysiologic laboratory is first described for the first time in this paper. All the parameters of this method were as follows: (1) pulse duration: 10 ms; (2) pulse rate: 250-300 bpm; (3) pulse amplitude: 26-43 volts; (4) number of pulse from each supra-burst pacing: 3-5 beats. The results of terminating PSVT using this method showed that (1) among 112 patients with PSVT treated by this method, PSVT was terminated in 103 cases and failed to terminate in 9 cases; (2) during each PSVT successfully terminated by this method, once (90.4%), twice (6.6%), thrice time (3%) supra-burst pacing were respectively used. These data indicate that transesophageal supra-burst pacing is a safe, simple and useful method to terminate PSVT.
