Table 3.

Bruce protocol test duration in a group of young subjects with congenital heart disease compared to what has been reported in the literature for healthy subjects of the same age (25). The overall group was divided into tertiles based on the expected test duration (the first tertile has the lowest exercise tolerance).

	Test Duration Pre (s)	Test Duration Post (s)	Difference in Respect to Expected Values Pre (s)	Difference in Respect to Expected Values Post (s)
First Tertile	488 ± 81 ^&	519 ± 106 &	−273 ± 72 ^&	−242 ± 98 ^&
Second Tertile	574 ± 56 &	569 ± 79 &	−126 ± 22 &	−130 ± 77 &
Third Tertile	584 ±.112 ^	593 ± 116 ^	−140 ± 116 ^	−131 ± 122 ^

^ = p < 0.005 comparing the second tertile with the others at each time point (pre or post); & = p < 0.005 comparing the third tertile with the others at each time point (pre or post).
