Detecting Atrial Fibrillation Might Prevent Stroke by Karishma Abhishek on June 2, 2021 at 11:46 PM Improved detection of atrial fibrillation (AF) using an implantable device over 12 months is found to be more than three times effective at detecting the condition when compared to standard care and could also help in preventing disabling strokes, as per The Post-Embolic Rhythm Detection With Implantable Versus External Monitoring (PER DIEM) study, at the University of Alberta and University of Calgary, published in the journal JAMA. Atrial fibrillation (AF) is one of the prevalent heart rhythm disorders that results in an irregular heartbeat. It is known to increase the risk of stroke, and even heart failure. The study anticipates to significantly change the practice in how clinicians look for AF in Albertan patients following ischemic stroke.
