Feeding behavior modifies the circadian variation in RR and QT intervals by distinct mechanisms in mice.

Article Synopsis
- Rhythmic feeding behavior in mice influences the 24-hour variations in heart rate (RR intervals), ventricular repolarization (QT intervals), and core body temperature, with significant findings from telemetry data analysis.
- Altering feeding times affects the phase and amplitude of these rhythms, showing that heart rate changes are linked to autonomic signaling, while QT interval changes are more aligned with core body temperature variations.
- The study concludes that while feeding behavior impacts the autonomic regulation of heart rate, core body temperature primarily drives the variations seen in ventricular repolarization.
Rhythmic feeding behavior is critical for regulating the phase and amplitude in the ≍24-hour variation of the heart rate (RR intervals), ventricular repolarization (QT intervals), and core body temperature in mice. We hypothesized the changes in cardiac electrophysiology associated with feeding behavior were secondary to changes in core body temperature. Telemetry was used to record electrocardiograms and core body temperature in mice during ad libitum-fed conditions and after inverting normal feeding behavior by restricting food access to the light cycle.
