Key result
The Apple Watch shows promise for detecting myocardial infarction by recording multiple-lead ECG signals, but current evidence is limited to small proof-of-concept studies and case reports.
Why the study?
Outcomes after myocardial infarction depend on time to treatment, yet delays between symptom onset and treatment are common.
Can the Apple Watch be used to record multiple-lead electrocardiograms for diagnosing myocardial infarction?
Can the Apple Watch be used to record multiple-lead electrocardiograms for diagnosing myocardial infarction?
The Apple Watch shows encouraging potential for recording multiple-lead ECGs to detect myocardial infarction, which could eventually decrease time to treatment, but further research is required.

Apple Watch multiple-lead ECG for MI detection remains investigational; leaves open need for larger prospective validation before any clinical role.
Although the outcome after myocardial infarction depends on the time to treatment, a delay between symptom onset and treatment is common. Apple Watch, a popular wearable device, provides the ability to perform an electrocardiogram. We review the progress made in using the Apple Watch to record multiple electrocardiogram leads for diagnosing myocardial infarction. Although the data are encouraging, many limitations remain, and more research is needed. Nevertheless, the Apple Watch could eventually serve as a self-check tool for patients who have chest pains or other symptoms of myocardial infarction, thus substantially decreasing the time to treatment and improving the outcome after myocardial infarction.

Li et al. (2022) conducted a review in Myocardial Infarction. Apple Watch vs. Standard 12-lead ECG was evaluated. The Apple Watch shows promise for detecting myocardial infarction by recording multiple-lead ECG signals, but current evidence is limited to small proof-of-concept studies and case reports.
