Factor Information
Data ID 3624
Factor Heart rate (Delta-HRp)
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 <0.001
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.

Title Negative chronotropic response to low-dose atropine is associated with parasympathetic nerve-mediated cardiovascular response in postoperative patients with congenital heart disease.
Sample
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.
