This study examines the relationship between heart rate, sympathetic activation, and the force-frequency relationship in HFrEF patients and controls, finding a bidirectional link with optimal heart rate targets likely being individual.

This study evaluates the autonomic effects of transcutaneous auricular nerve stimulation at four ear sites, finding that heart rate variability changes significantly across all sites with baseline LF/HF ratio predicting response.
