title: iOS application reading in ECG data from healthkit instead of photoplethysmography
body: <p>Last year I built an iOS application that reads in workouts from Healthkit. These workouts were recorded by the Apple Watch in built fitness application and gathers heart rate information using photoplethysmography (the light sensor in the watch before the ECG). </p>
  
  <p>I want to get the new Apply Watch with the ECG monitor. If I record a workout in the same manner as above, will the data from the ECG still be passed into Healthkit and will my mobile application therefore be able to read the workout from Healthkit and all the relative heartrate data?</p>
  
  <p>I'm hoping I don't need to perform any updates on my mobile application now that the apple watch has an ECG and not the photoplethysmography.</p>
  
  <p>Does the new Apple Watch come with both photoplethysmography and the ECG or just the ECG?</p>
