CTOnews.com August 17-Apple Watch users may actually be using their watch to detect symptoms of a heart attack. According to a study published earlier this month in the Journal of the Texas Heart Institute, Apple Watch can help identify heart attacks through an electrocardiogram (ECG) sensor included in the watch.

In the journal, researchers discuss the topic, and more development is needed, but Apple Watch has the potential to be a self-checking tool for users. Heart attacks or myocardial infarction (MI) are becoming more common in the United States, with someone experiencing one almost every 40 seconds. If treated quickly, the chances of survival increase by more than 50%, so early detection can help save millions of lives.

Apple says the device isn't suitable for detecting myocardial infarction because it provides only single-lead information, whereas professional diagnosis requires a 12-lead ECG. Research shows that Apple Watch has potential, especially Apple Watch Series 4, 5, 6 and 7 models, because they have ECG sensors that can provide multiple leads for MI diagnosis. It explains that leads I, II and III are essential in traditional ECG diagnostic methods. Since Apple uses Lead I, it only needs two more to get relevant information using different body parts.

The study notes that "a smartwatch can be placed on the left lower abdomen, left thigh or left ankle, and lead II can be recorded by placing the right index finger on the crown; lead III can be recorded in the same way by placing the left index finger on the crown." "

The researchers note that it is also important to note the limitations of this approach, as Apple Watch is not yet a substitute for clinical procedures.
