AliveCor, which has developed an FDA-cleared smartphone-enabled ECG device, has launched a clinician-facing app using artificial intelligence to pick up signs of atrial fibrillation earlier, according to a company news release. It's an interesting development for the business because it can alert physicians to patients with an elevated risk of having a stroke. The Kardia Pro app is for clinical use. But the goal is to analyze data from patients that includes weight, activity and blood pressure with AI to personalize the heart profiles of each patient, the news release said. An estimated 795,000 people suffer a stroke each year, the majority of them for the first time.
