心房細動

Atrial fibrillation (AF, ATFB) is the most common cardiac arrhythmia and is regarded generally as a sporadic, acquired disorder. Nevertheless, recent growing evidence points to an important heritable basis for AF. By linkage analysis, several loci have been mapped for monogenetic AF. Some of these loci encode for subunits of potassium channels.
