According to study published in the Texas Heart Institute Journal, the Apple Watch could be used to monitor for heart attack symptoms (via MyHealthyApple).
A myocardial infarction happens when the blood supply to the heart is blocked and some of the heart muscle does not get adequate oxygen. The electrocardiogram (ECG) capability on Apple Watch Series 4, 5, 6, and 7 models has been studied by researchers from the Texas Heart Institute to help diagnose myocardial infarction symptoms. This feature allows users to record several ECG leads on various body areas.
How soon after a heart attack treatment begins determines the results. Within an hour of the onset of symptoms, more than half of myocardial infarction patients pass away in an emergency room or before getting to a hospital. According to the research, the Apple Watch may be able to accurately predict the likelihood of a heart attack as soon as symptoms appear, alert the wearer to seek immediate medical attention, and shorten the time it takes for treatment.
The 12-lead electrocardiogram is the standard method used by doctors to confirm myocardial infarction; however, the Apple Watch records a single-lead ECG utilising a positive electrode on the back of the device and a negative electrode on the Digital Crown. As a result, while the Apple Watch could not replace high-quality medical equipment used in hospitals, it could offer a fresh screening method for other settings.
As numerous studies have demonstrated, the Apple Watch can record multiple-lead ECG readings that precisely detect the ST change during a heart attack, the researchers assert that the gadget has promise for diagnosing myocardial infarction. Although further clinical evidence is needed, the continuing study offers a sneak peek at one of the innovative health-monitoring features that may eventually be an official Apple Watch feature.
