AliveCor emphasizes that this will only help “inform” chats with your doctor, not replace them. This still isn’t as sophisticated as a multi-lead ECG you’d receive at a clinic or hospital. However, it could be useful even if you’re in fine health. It should reduce the number of inconclusive ECG results you see, and provide a clearer picture of your heart’s performance than before. Don’t be surprised if other devices follow suit.
