Successful transesophageal pacing in a very-low-birth-weight-infant with atrioventricular block.

A baby with complete atrioventricular block was born with a birth weight of 1403 g. Isoproterenol was ineffective and emergency pacing was required. Since transcutaneous pacing was ineffective and transvenous pacing was untenable due to small body size, transesophageal pacing was performed for 3.5 hours until permanent pacemaker implantation. There were no complications. This is the first report of continuous transesophageal pacing in a very-low-birth-weight infant.
