Pull or Fetch real time heart rate data for alert

[nattaporn_np]

I'm developing a university project about alerting the Arrhythmia of the heart rate in real time.If it possible to pull or fetch the real time heart rate data when we're running, so we can use that data to alert the emergency to the user on the web application. Is the fitbit Ionic possible to work with this?

for real time alerts, I would rather measure hrm data and do the calclations in the watch app,

web API would always be slower, plus it is aggregated, so not suitable for your usecase. 

There is an example app that wild be useful for you here :  https://dev.fitbit.com/build/tutorials/examples/

Thank you for your advise.Can we fetch the heart rate data realtime through the web API and show the realtime heart rate on my website during the activity, is it possible?

The Web API is not real-time. It only updates when the watch syncs.
