It’s September 12, which means today is the day Apple announces new products. Is today also the day that Apple reveals its latest Watch with the rumored integrated EKG? The Watch on its own has already saved one person’s life – a teen whose device alerted her to an abnormally high heart rate – which inspired Apple CEO Tim Cook to tweet about the news.

Late last year, the FDA approved the first medical device accessory for the Apple Watch, so today could very well be The Day. The KardiaBand, produced by AliveCor, pairs a sensor with an app that can identify abnormal heart rhythm and atrial fibrillation. The wearer can touch the sensor on the Watch’s band and receive an EKG reading in 30 seconds. According to a Bloomberg article, the KardiaBand “uses a neural network to predict and analyze the wearer’s heart rate based on his or her history and a trove of cardiovascular data from both sick and healthy people. The device measures the heart rate every five seconds and tells users when it’s out of their expected range. It doesn’t apply a generic range—instead, it determines what’s abnormal for you.”

We’ll be keeping an eye on revelvant announcements during today’s live event – stay tuned!
