Text: All parameters increased significantly after cardiac rehabilitation (P < 0. 01) : SD of all normal RR intervals 123. 4 + / -30. 0 versus 123. 8 + / -30. 0 ms ; SD of the averages of normal RR intervals in all 5-min segments of the entire recording 115. 1 + / -30. 5 versus 116. 3 + / -28. 3 ms ; mean of the SD of all normal RR intervals for all 5-min segments of the entire recording 49. 0 + / -12. 5 versus 48. 3 + / -11. 8 ms ; square root of the mean of the sum of the squares of differences between adjacent RR intervals 29. 7 + / -9. 1 versus 28. 0 + / -8. 5 ms ; percentage of differences between adjacent RR intervals > 50 ms 7. 9 + / -6. 0 versus 7. 1 + / -6. 1 % (group A versus group B, respectively, NS).
