The Mayo Clinic ECG Study app allows Mayo Clinic patients who own an Apple Watch Series 4 or later to transfer data from Apple’s ECG app (via the Apple Health app and HealthKit) to Mayo Clinic in order to participate in an ECG research study conducted by Mayo Clinic. The objective of the study is to determine if the ECGs obtained from an Apple Watch are of sufficient quality to guide a person’s care.

You must be a Mayo Clinic patient with a Patient Online Services account and have signed a study consent form to use this app.
