Peak MAP and HR responses to neck pressure and neck suction in control and PEMI situations
| Neck pressure | Neck suction | |||
|---|---|---|---|---|
| NP50 | NP30 | NS60 | NS30 | |
| ΔMAP (mmHg) | ||||
| Control | 5.8 ± 0.9 | 5.8 ± 0.7 | −10.5 ± 0.6 | −9.6 ± 1.1 |
| PEMI | 9.0 ± 1.2* | 7.0 ± 0.9 | −8.3 ± 0.9* | −5.6 ± 0.8* |
| ΔHR (beats min−1) | ||||
| Control | 3.8 ± 1.1 | 3.7 ± 0.9 | −7.1 ± 1.7 | −3.6 ± 0.9 |
| PEMI | 4.0 ± 1.2 | 3.5 ± 1.0 | −6.8 ± 2.0 | −4.4 ± 1.2 |
Values are means ± s.e.m.Δ MAP, change in mean arterial pressure from baseline values. Δ HR, change in heart rate from baseline values. PEMI, post-exercise muscle ischaemia.
