Apple gave us a hint of where the Watch was headed last year when it announced new heart-tracking features and a Stanford-led study to detect atrial fibrillation. Apple has broken new ground by adding an inbuilt electrocardiogram ( ECG ) to the Apple Watch Series 4 . The ECG has the ability to collect heart sounds in real time , so that symptoms of heart disease , such as atrial fibrillation and irregular or rapid heart rates , can be tracked even if a patient is n’t with a doctor . The watch itself records heart readings for doctors and can send the patient messages , alert them to any potential heart attack .
