F | p-value | |||
---|---|---|---|---|---|
Normal | Slow-paced | Mechanically assisted | |||
Heart rate (beats per minute) | 64.25 (8.1) | 64.72 (9.9) | 63.50 (9.4) | 0.36 | 0.705 |
MAP (mmHg) | 82.53 (6.7) | 79.97 (8.6) | 89.24 (10.2) | 2.38 | 0.143 |
sBRS (ms/mmHg) | 15.46 (9.1) | 12.19 (4.8) | 13.62 (7.1) | 1.40 | 0.280 |
RMSSD (ms) | 49.97 (19.6) | 39.50 (9.3) | 48.69 (13.9) | 2.25 | 0.142 |
Respiratory rate (breaths per minute) | 12.54a (1.0) | 4.41b (0.7) | 5.45b (1.0) | 74.30 | 0.000 |
Notes:
When superscripts are the same between two conditions on a measure, post hoc comparison indicates no significant difference between condition means. When superscripts are different, post hoc comparison indicates significant difference between group means at p<0.01.
Abbreviations: SD, standard deviation; MAP, mean arterial pressure; sBRS, spontaneous baroreceptor sensitivity; RMSSD, root mean square of the SD of normal-to-normal intervals.
