“Scientists at The Ohio State University Wexner Medical Center also discovered that atrial fibrillation drivers don’t always have the shape of a closed loop but may instead consist of “hubs” where the electrical activity of atrial fibrillation is multiplied much like a small tornado. The study results were reported in The Journal of the American Heart Association.
“Thinking of atrial fibrillation drivers as hubs may change the way we interpret mapping results of the heart to identify these drivers. Finding these reentrant atrial fibrillation drivers is key for doing targeted ablation and successfully treating AFib,” said Vadim Fedorov, professor of physiology and cell biology at the Ohio State College of Medicine and lead author of the study.
At least 2.7 million Americans live with atrial fibrillation, with some suffering from persistent atrial fibrillation that lasts for longer than seven days at a time. When medications don’t work, physicians use ablation.”
