How the Apple Watch is able to detect symptoms of a heart attack

Myocardial infarction, more generally called heart attack, occurs when the heart no longer receives enough oxygen to function properly, the fault of one or more arteries clogged with cholesterol.

Research teams from the Texas Heart Institute used an Apple Watch equipped with an ECG system for their work. They demonstrated that by placing the watch on the chest, in different places close to the heart, and taking several ECGs on its different positions, the results can indicate certain warning signs of a heart attack.

Obviously, in the event of abnormally high results, it is recommended to consult a health professional urgently. If the results of the Apple Watch are generally reliable, they do not replace extensive medical analyzes with suitable equipment. Apple remains cautious and clearly indicates when performing an ECG that this device cannot be used to prevent a heart attack.

The Apple Watch Series 8, which will be unveiled next September, could integrate a temperature sensor according to various online rumors for several months.
