New technique helps spot atrial fibrillation genetic variations

A technique called whole-exome sequencing (WES) has been used for the first time at Vanderbilt University to identify new genetic variations associated with a common disease — a heart rhythm abnormality called atrial fibrillation (AF).

Rhythm response tied to gene variant

A genetic variant that increases risk for atrial fibrillation also impacts the response to a common therapy for the heart rhythm disorder.

Study points to personal treatment for atrial fibrillation

Individuals with atrial fibrillation who have a particular genetic variant respond better to rate control therapy.
