Resting levels of cardiovascular variables from 10 min of resting data in conscious normal (n= 6) and HF (n= 5) sheep, before and after bilateral PVN microinjection of glycine
| Normal | Heart failure | |||
|---|---|---|---|---|
| Control | After glycine | Control | After glycine | |
| Mean arterial pressure (mmHg) | 78.1 ± 2.1 | 78.0 ± 3.7 | 72.8 ± 1.7 | 74.3 ± 1.7 |
| Heart rate (beats min−1) | 84.2 ± 3.1 | 82.8 ± 3.3 | 104.3 ± 9.5 * | 109.7 ± 12.5 |
| CSNA burst incidence (bursts (100 heart beats)−1) | 46.7 ± 5.5 | 43.3 ± 5.1 | 86.5 ± 4.1 * | 80.0 ± 2.5 |
| CSNA burst frequency (bursts min−1) | 38.7 ± 3.9 | 36.3 ± 4.2 | 91.2 ± 9.9 * | 91.6 ± 17.0 |
Data are means ± SEM; *P < 0.05 vs. control values in normal group.
