- Researchers at the Mayo Clinic used AI and an Apple Watch to detect a weak heart pump.
- The researchers developed an algorithm that used the signal from an Apple Watch ECG to detect the condition.
- The study's accuracy was "as good as or slightly better than a medical treadmill test."
Researchers at the Mayo Clinic developed an algorithm that, using the ECG from an Apple Watch, could identify patients with a weak heart pump.
In a post on the Mayo Clinic website, researchers announced the results of the study which was also presented at the Heart Rhythm Society conference on Sunday, May 1.
Paul Friedman, M.D., chair of the Department of Cardiovascular Medicine at Mayo Clinic in Rochester, said that researchers were able to use AI and the ECG signal from the Apple Watch rather than "an expensive, sophisticated imaging test, such as an echocardiogram, CT scan or MRI."
You can watch Dr. Paul Friedman discuss the technology on YouTube below:
Itzhak Zachi Attia, Ph.D. lead the effort to use AI in order to adapt the Apple Watch's ECG signal into something that could be used to detect the medical condition. According to the report, participants in the study securely transmitted 125,610 ECGs over the course of the six-month study. Attia says that the accuracy of their data is "as good as or slightly better than a medical treadmill test."
Dr. Friedman says that the next step will be to expand the study internationally. It's currently unclear if such a feature will eventually be built into the Apple Watch's Health app.
