| Factor Information | |
|---|---|
| Data ID | 3557 |
| Factor | Baseline HR (heart rate) (bpm) |
| Description | In the complex CHD patients, higher cNCR was mainly associated with the lower pharmacologically determined cardiac parasympathetic nervous tone (PST), HR variability, high atrial natriuretic peptide, and lower right ventricular ejection fraction ( p<0.0001). |
| Biomarker | NA |
| Classification | E11 (physiological factor - physical sign) |
| Association | |

| 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 | <0.05 |
| Conclusion | Baseline HR was higher in the Fontan patients. NCR and cNCR were significantly smaller and higher, respectively, in the CHD groups, especially in the complex CHD and 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. | |
