| Popis: | The ventilatory response to graded treadmill exercise was studied in 50 children with congenital heart disease (CHD), a left-to-right intracardiac shunt, and compared to that of age and sex-matched healthy children. In all these children, a breakpoint in the minute ventilation\((\dot V_E )\) in relation to increasing oxygen uptake\((\dot VO_2 )\) was detected. Because of the reported coincidence of the nonlinear increase in\(\dot V_E \) and lactate with increasing\(\dot VO_2 \), this threshold has been named “ventilatory anaerobic threshold” (VAT), expressed in ml O2·min−1·kg−1. VAT correlated well with\(\dot VO_2 \) (ml·min−1·kg−1), reached at a heart rate of 170/min\((\dot VO_{2,170} )\). Compared to normal children, however, a significantly (p |
