Key result
Genetic factors demonstrated considerable heritability for heart period (37%-48%), RSA (40%-55%), and respiration rate (27%-81%), with common genes explaining large portions of their covariance.
Observational (n=780)
Common genes explain large portions of the covariance between heart period, respiratory sinus arrhythmia, and respiration rate, which could aid linkage studies for cardiovascular disease risk.
No takes yet. Share an insight, caveat, or question.
No immediate clinical implications for autonomic assessment; leaves open shared genetic influences on cardiorespiratory traits for targeted studies.
Kupper et al. (2005) conducted an observational in Healthy (n=780). Genetic factors was evaluated on Heritability of ambulatory heart period, respiratory sinus arrhythmia (RSA), and respiration rate. Genetic factors demonstrated considerable heritability for heart period (37%-48%), RSA (40%-55%), and respiration rate (27%-81%), with common genes explaining large portions of their covariance.
