Spectral analysis showed a trend toward an increased low-frequency to high-frequency ratio in patients (p = 0.08) suggesting sympathetic predominance.

The low-frequency to high-frequency ratio was higher in the combined HC group compared the controls with a trend toward significance (p = 0.08; Figure 3 ).
When HR recovery was normalized to the difference between HR at peak exercise and rest, the HRR was lower in the obstructive group but did not reach statistical significance at 1 and 2 minutes.
