Cannon, M.D. ResearchMayo Clinic researchers with training in heart rhythm disorders study the diagnosis of heart conditions using electrocardiograms and other techniques in Mayo Clinic's Cardiovascular Research Center. Monitoring ECGs The experts of the Heart Rhythm and Physiological Monitoring Laboratory at Mayo Clinic research ways to improve the use of ECGs for people with heart conditions. Some areas of research include: Applying artificial intelligence with electrocardiograms to better diagnose and predict atrial fibrillation (AFib) and to diagnose conditions that have not been traditionally diagnosed with an electrocardiogram. Learning how ambulance ECGs affect the outcomes of people having a heart attack. Evaluating the overuse of certain heart tests in people with typical ECGs. Improving the use of ECGs to guide heart procedures called catheter ablation. At Mayo Clinic, you may have the opportunity to participate in clinical trials.
