Dear Editors and Readers
I have read with attention the article “Novel use of Apple Watch 4 to obtain 3-lead electrocardiogram and detect cardiac ischemia.”1 Dr Avila should be commended for his stimulating manuscript showing the use of the Apple Watch to obtain Einthoven leads II and III readings. The cases illustrating ST-elevation in inferior acute myocardial infarction are really interesting.
An evident limitation of the approach suggested in the article is its “inability to detect precordial leads, which could miss cardiac ischemia in other cardiac regions.”1 To solve this problem, I have recently shown my method to record a quasistandard electrocardiogram, including the precordial leads, in the European Congress of Cardiology2 and in the Annals of Internal Medicine.3
Obviously, I agree with Dr Avila that the use of the Apple watch to detect acute ischemic events requires a wide range of clinical studies. But the future is coming!
