Summary

This research investigates using light-sensitive proteins to control cardiac electrical activity and treat arrhythmias. By precisely guiding heart rhythms with light rather than drugs or shocks, the study identifies proteins capable of suppressing dangerous premature signals, offering a reversible, non-invasive alternative to current heart disease treatments.
