Research indicates (refer to links below) that it is possible to detect potential Heart Attack based on Heart Rate and Heart Rate zones. Fitbit watches constantly monitor heart rate and theoretically it should be possible to detect potential heart attack based on abnormal heart rate and resting heart rate's trend.
- Emergency SOS: Fitbit device should trigger alert on paired mobile phone which sends out a SOS message along with geo-location to pre-configured address to ensure timely medical assistance.
- Preventive Alert: Fitbit should alert the user if it sense potential Heart Attack based on current & resting heart rate patterns or change to a different heart rate zone.
