May enable ambulatory autonomic monitoring; leaves open prospective clinical validation.
A novel point process adaptive filter algorithm provides accurate dynamic estimation of respiratory sinus arrhythmia, offering a potential framework for ambulatory monitoring of autonomic control.
Chen et al. (2009) studied Autonomic control and respiratory sinus arrhythmia. Point process adaptive filter algorithm was evaluated on Tracking heart beat intervals and dynamic estimate of RSA gain. A point process adaptive filter algorithm accurately described heart beat data and confirmed established findings of vagally mediated respiratory sinus arrhythmia.
