Hayter, E.A., Wehrens, S.M.T., Van Dongen, H.P.A. et al. Distinct circadian mechanisms govern cardiac rhythms and susceptibility to arrhythmia. Nat Commun 12, 2472 (2021). https://doi.org/10.1038/s41467-021-22788-8 Abstract Electrical activity in the heart exhibits 24-hour rhythmicity, and potentially fatal arrhythmias are more likely to occur at specific times of day. Here, we demonstrate that circadian clocks within the brain and heart set...
