Text: Compared with the control group, CRT led to significant short and long term improvements in functional NYHA functional class (mean (SEM) 2. 1 (0. 4) v 2. 8 (0. 4) at 24 months, p < 0. 05), mean ejection fraction (25. 7 (4) % v 21. 1 (5) % at 24 months, p < 0. 05), peak Vo (2) (16. 8 (3. 9) v 12. 6 (3. 5) ml/kg x min at 24 months, p < 0. 01), and Vo (2) at anaerobic threshold (14. 4 (3. 7) v 10. 8 (3. 2) ml/kg x min at 24 months, p < 0. 05).
