A conversation with Mayo Clinic experts in AI for cardiology

How Mayo Clinic cardiologists and AI scientists are transforming the electrocardiogram into a powerful tool for earlier, more-equitable detection of heart disease.

Mayo Clinic experts in AI, Francisco Lopez-Jimenez, M.D., M.S., and Zachi Attia, Ph.D., M.B.A., share how artificial intelligence (AI) is reshaping cardiovascular care by unlocking new insights from the electrocardiogram (ECG). Over the past decade, Mayo Clinic researchers have reimagined the ECG as a rich physiological signal rather than a limited diagnostic checklist. By applying AI models to routine ECGs, clinicians can now identify patients at risk of conditions such as heart failure, atrial fibrillation and cardiomyopathy — often before symptoms appear. The conversation highlights how AI-enabled ECG tools support earlier diagnosis, guide more-appropriate use of electrocardiography and help clinicians make more-consistent, informed decisions without replacing clinical judgment.
