Light therapy's effectiveness in treating atrial fibrillation.
Researchers have found that optogenetics, a light-based technology, could be used to treat atrial fibrillation (AFib) by modifying targeted cells in rats to restore a regular rhythm to hearts affected by AFib. The technique could fully penetrate the atrial wall in humans to treat the heart condition, offering a shock-free option for treating AFib or irregular or rapid heart rate. However, experts say the findings are interesting, but they aren’t sure light therapy will replace the current treatments for AFib.
