| Abstract |
|
Atrial flutter is an infrequent, but potentially unstable tachyarrythmia that occurs in pediatric ages.
Transesophageal atrial pacing was used for treatment of 10 episodes of atrial flutter in 7 patients. At the time of atrial flutter conversion, patients were 6 days to 14 years old. 6 patients had associated with congenital heart disease.
The atrial cycle length of atrial flutter ranged from 140 to 280 msec with variable atrioventricular conduction. Transesophageal atrial pacing was performed using a bipolar 4 F transesophageal electrode catheter. Atrial flutter conversion was accomplished with stimulation bursts using about 5 seconds of stimuli, 10 msec in duration at 20 to 27 mA. Pacing cycle length was 45 to 110 msec less than the atrial cycle length of tachycardia in 6 episodes. But in a neonate, underdrive pacing converted atrial flutter to sinus rhythm. Conversion attempts were unsuccessful on 2 occasions.
Transesophageal atrial pacing is a safe and effective, minimally invasive technique for treatment of atrial flutter in infants and children. |
