Scientists in Japan have found a potential marker to identify which people with abnormally fast heartbeats are at high risk of developing heart failure.
The results were published in June in Circulation: Genomic and Precision Medicine, a journal from the American Heart Association.
Atrial fibrillation, or chronically, abnormally fast heartbeat, can be a symptom of a potentially fatal disease known as tachycardia-induced cardiomyopathy (TIC). The condition can be reversed and damage can be prevented, but only if the heartbeat is brought back into proper rhythm through drugs or catheter therapy.
