| Application | treatment and prognosis |
| Objective | To investigate the negative chronotropic response (NCR) to low-dose atropine in postoperative patients with congenital heart disease (CHD). |
| p Value | <0.001 |
| Conclusion | NCR is attenuated in proportion to the impaired cardiac parasympathetic nervous system and hemodynamics in postoperative complex biventricular CHD patients. In addition to PST, β sensitivity of the sinus node significantly influences the NCR in Fontan patients. |

| Population | All (9-36 years) | |
| Source | patients | |
| Region | Osaka, Japan | |
| Method | NCR corrected for basal heart rate (HR) (minimal HR/basal HR=cNCR) was determined after low-dose atropine (3 Ag/kg) administration and was compared with the cardiac autonomic nervous and functional status. | |
