How Wearables Are Detecting Invisible Heart Rhythm Issues

In episode 149, Lucas and Luna explore how smartwatches and fitness trackers are quietly catching atrial fibrillation — the most common serious heart rhythm disorder — often before symptoms appear. They break down the real-world data behind single-lead ECG sensors, the difference between a medical-grade diagnosis and a consumer alert, and what happens when your watch tells you to see a doctor. With stories from actual users and insights from cardiologists, they explain why these alerts are changing emergency rooms and preventive care. Plus, they discuss the limits of the tech — false alarms, anxiety, and the need for clinical follow-up. If you've ever wondered whether your watch's heart notifications are worth paying attention to, this episode gives you a clear picture of what the technology can and can't do today. #AtrialFibrillation #SmartwatchECG #WearableHealth #HeartHealth #HealthTech #WearableTech #ECGSensor #Cardiology #FitnessTracker #AppleWatch #SamsungGalaxyWatch #PreventiveCare #DigitalHealth #MedicalDevice #FexingoBusiness #BusinessPodcast #TechPodcast #WearableTechPodcast Keep every episode free: buymeacoffee.com/fexingo
