A joint study by Göttingen University Medical Center (UMG) and Würzburg University Hospital provides new insights into why heart muscle cells lose their rhythm in atrial fibrillation. Disrupted calcium communication between central cell structures in the heart could be a decisive mechanism in this process. The findings have been published in the journal Circulation Research.

The cytoskeleton, which supports the structure of the cells and contributes to the orderly organisation of the mitochondria, is shown in magenta. Image: Circulation Research
