通过HRV跟踪心跳心跳苹果手表
通过HRV跟踪心跳心跳苹果手表
提问于 2017-10-31 16:56:13
我在研究如何获得不同心跳间隔的节拍间隔。
我戴着苹果手表，现在可以出口

</Record>然而，当我得到一个heartRateVariabilitySDNN的样本时，我只得到两个值。
这是我用来获取示例的代码
let healthStore = HKHealthStore()
var typeHeart = HKQuantityType.quantityType(forIdentifier: .heartRateVariabilitySDNN)
var startDate = Date() - 7 * 24 * 60 * 60 // start date is a week
var predicate: NSPredicate? = HKQuery.predicateForSamples(withStart: startDate, end: Date(), options: HKQueryOptions.strictEndDate)
let sampleType = HKSampleType.quantityType(forIdentifier: HKQuantityTypeIdentifier.heartRateVariabilitySDNN)
let sortDescriptor = NSSortDescriptor(key:HKSampleSortIdentifierStartDate, ascending: false)
let sampleQuery = HKSampleQuery(sampleType: sampleType!, predicate: predicate, limit: 30, sortDescriptors: [sortDescriptor])
{ (sampleQuery, results, error ) -> Void in
if(error == nil) {
print(results)
}
}这就是它所输出的一切：
Optional([92.3536 ms D7627860-F87C-4316-9943-522BC1D6734B "Apple Watch" (4.0), "Watch3,4" (4.0)"Apple Watch" (2017-10-31 13:48:19 +0000 - 2017-10-31 13:53:30 +0000), 92.7156 ms EB0DBCB1-164A-4D50-9103-270F3F9FBCD1 "Apple Watch" (4.0), "Watch3,4" (4.0)"Apple Watch" (2017-10-31 13:40:43 +0000 - 2017-10-31 13:41:54 +0000)])它们基本上是两个值: 92.7ms和92.3ms。这是在“呼吸”应用期间的平均2次训练。
有人知道我如何获得InstantaneousBeatsPerMinute和/或HRV元数据吗？
编辑:似乎有一些有趣的事情在进行，输出的值看起来非常像XML中Record类型的打印语句。

在向苹果( Apple )提交技术支持事件(TSI)后，他们表示，目前不可能做到这一点。
感谢您联系苹果开发者技术支持(DTS)。我们的工程师已经审查了您的要求，并得出结论，在当前的运输系统配置中，没有支持实现所需功能的方法。 如果你想让苹果公司考虑在将来增加对这些功能的支持，请通过https://developer.apple.com/bug-reporting/的Bug工具提交一个增强请求。
如果你想看到这个功能，请提交一个错误报告！

在iOS 13中，苹果发布了新的心跳系列API。您可以在这里找到更多详细信息：

这个相关的WWDC视频会话对于理解这个新API：https://developer.apple.com/videos/play/wwdc2019/218非常有用。

如果你想获得瞬时心率，你的应用程序应该启动一个HKWorkoutSession。
self.workoutSession = HKWorkoutSession(activityType: .Running, locationType: .Indoor)
self.workoutSession!.delegate = self;
self.healthStore.startWorkoutSession(self.workoutSession!)
Then, you can start a streaming query from HKHealthKit to give you updates as HealthKit receives them:
let distanceType = HKObjectType.quantityTypeForIdentifier(HKQuantityTypeIdentifierDistanceWalkingRunning)
let predicate = HKQuery.predicateForSamplesWithStartDate(workoutStartDate, endDate: nil, options: .None)
let distanceQuery = HKAnchoredObjectQuery(type: distanceType!, predicate: predicate, anchor: 0, limit: 0) { (query, samples, deletedObjects, anchor, error) -> Void in
// Handle when the query first returns results
// TODO: do whatever you want with samples (note you are not on the main thread)
}
distanceQuery.updateHandler = { (query, samples, deletedObjects, anchor, error) -> Void in
// Handle update notifications after the query has initially run
}
