Monitoring for Individual Triggers May Reduce Episodes of Atrial Fibrillation

November 17, 2021 — People with atrial fibrillation (AFib) who underwent individualized testing to discover triggers for their irregular heartbeats reported less frequent irregular episodes, according to late-breaking research presented today at the American Heart Association’s Scientific Sessions 2021

In the I-STOP-AF Trial, “Individualized Studies of Triggers of Atrial Fibrillation: A Randomized Controlled Trial,” researchers set out to determine whether monitoring potential triggers could reduce AFib episodes.

“There has been little research done on whether perceived triggers of AFib actually lead to AFib episodes,” said Gregory Marcus, M.D., M.A.S., the study’s lead author, a professor of medicine at the University of California, San Francisco School of Medicine and associate chief of cardiology for research at UCSF Health. “Our research team aimed to determine whether perceived triggers equate to actual triggers—and whether tracking triggers for AFib could lead to fewer episodes.”
