Theheart rate is recorded as PPG waveforms by the Apple watch during periods of minimal arm movement. Tachograms, which are heart rate over a period of time, are created. If a tachogram detects irregular heart rate, then the algorithm is triggered to get 4 confirmatory tachograms with irregular pulse rates during minimal arm movements.
Thisfirst graph is the heart rate readings from both devices plotted on the same figure. Y axis is the HR values and X axis is the time. I started running at 9:25am and finished at around 9:58am
Seea graph of your heart rate data. Open the Heart Rate app on your Apple Watch. Turn the Digital Crown to Range, Resting Rate, or Walking Average to show your heart rate
