Abstract

Because we have observed a relatively large number of tricuspid atresia patients with a short P-R interval and slurring of the initial QRS pattern suggesting preexcitation, we conducted a retrospective study to determine the frequency of this electrocardiographic pattern and whether or not this represented the presence of a true atrioventricular bypass tract.
