ECG Recorder for Polar H10 のアプリ分析 5月18日

Record ECG, heart rate, R-R intervals, and HRV with your Polar H10. This app connects to the Polar H10 heart rate sensor and records three raw data types: electrocardiogram (ECG), heart rate (HR), and R-R intervals (RR). It can also calculate heart rate variability (HRV) from the recorded RR intervals. Minimum H10 firmware version required for ECG is 3.0.35. Live charts are available for ECG, HR, RR, and HRV. You can save screenshots of the live charts to Photos, and you can record videos of the live view using the iOS screen recorder from Control Center. With an active “Enable premium features” subscription (IN-APP purchase), recordings are saved to the app’s folder in the Files app using the recording start time as the file name. Premium features include: - Live ECG, HR, RR, and HRV charts - ECG export as .csv, .edf (EDF+), and legacy ascii text - HR and RR export as .csv and legacy ascii text - HRV export as .csv - PDF export of the last 30 seconds of the live ECG view on ECG-style A4 paper at 25 mm/s and 10 mm/mV - Apple Health export for heart rate, beat-to-beat timing, and HRV (SDNN) CSV exports now include local timestamps and elapsed seconds, so in most cases no separate time column has to be created manually. ECG DATA ECG data is recorded at 130 Hz according to specification (my device works at 130.061 Hz) in microvolts (µV). That means one value every 7.692 milliseconds. A 10 minute recording contains about 78000 values. ECG values can be divided by 1000 to convert them to millivolts (mV). The “Set marker” button in the live ECG chart adds a value of 2000 µV to the data so markers can be found easily in graphs or by searching the data. ECG recordings are also exported directly as .edf (EDF+) files and can be opened in the open source software EDFbrowser. Sample ECG data and demo videos for import into Apple Numbers and EDFbrowser are available here: https://ecgh10.app/ HR DATA About one heart rate value is recorded per second. RR DATA The RR interval is the time between two successive R-waves of the QRS signal on the electrocardiogram. RR intervals are recorded in milliseconds. HRV DATA HRV is calculated from accepted RR intervals and exported as RMSSD and SDNN in milliseconds. The app is free to download so you can connect to a device and get a first impression. A few seconds of the live charts can be viewed for free. To unlock all premium features, choose one of the available IN-APP purchases. Each subscription includes a one week free trial.
