Research

Mayo Clinic researchers trained in conditions that affect the heartbeat study the diagnosis of heart conditions using electrocardiograms and other tools in Mayo Clinic's Cardiovascular Research Center.

Topics of study include:

  • Using artificial intelligence (AI) with electrocardiograms (ECG) to help better find and predict atrial fibrillation (AFib).
  • Using AI and electrocardiograms to find conditions that an ECG traditionally hasn't been able to show.

At Mayo Clinic, you may have the opportunity to take part in clinical trials. Read more about the Heart Rhythm Disease Program in the Cardiovascular Research Center at Mayo Clinic.

Monitoring ECGs 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.
