Haemodynamic effects in both carvedilol and atenolol.
| Carvedilol (n = 12) | Atenolol (n = 12) | |||
|---|---|---|---|---|
| Pretreatment | Post-treatment | Pretreatment | Post-treatment | |
| Heart rate at rest (bpm) | 73.6 ± 2.2 | 66.8 ± 3.0 | 77.3 ± 3.1 | 62.5 ± 1.7 |
| Heart rate at peak exercise (bpm) | 137.6 ± 5.31 | 17.5 ± 5.5* | 136.1 ± 5.21 | 19.3 ± 4.1* |
| Systolic pressure at rest (mmHg) | 126.8 ± 3.01 | 19.4 ± 2.4* | 125.4 ± 2.61 | 16.3 ± 2.5* |
| Diastolic pressure at rest (mmHg) | 2.0 ± 2.5 | 69.8 ± 2.5 | 72.8 ± 2.7 | 67.5 ± 2.4 |
