Since the Apple Watch added the ECG app with the Series 4, numerous stories have surfaced about how the app has contributed to saving people’s lives. Now, a new article from the European Heart Journal tells the story of an 80-year-old woman in Mainz Germany whose Apple Watch detected evidence of a heart condition missed by a hospital ECG.
The woman arrived at University Medical Center Mainz complaining of chest pain, irregular heart rhythm, and lightheadedness. At the hospital, doctors performed a traditional 12-channel ECG, which revealed “no evidence for ischemia.”
The patient then showed doctors the results of ECG tests that she took with her Apple Watch, which included “tracings with marked ST-segment depression.” In these results, the doctors did see evidence of myocardial ischemia. The patient was transferred to the catheterization lab which showed “a left main stem stenosis and a left anterior descending/diagonal bifurcation lesion.”
Thus, the patient was treated with “coronary artery stenting” and left the hospital the next day. The Mayo Clinic describes myocardial ischemia as:
The article from the European Health Journal concludes that the Apple Watch can be used to detect myocardial ischemia:

Thus, the Apple Watch may be used not only to detect atrial fibrillation or atrioventricular-conduction disturbances but also to detect myocardial ischemia. An apple a day may keep myocardial infarction away.
