Optogenetics can be a promising shock-free approach to treat atrial fibrillation

New research published in the Journal of Internal Medicine demonstrates that optogenetics-;which uses light-sensitive proteins to control the activity of targeted cells-;is a promising shock-free approach to treating atrial fibrillation (AF), or an irregular, often rapid heart rate, for immediate restoration of regular rhythm.
