The most probable reason is that you are wearing an activity tracker or some other device that regularly captures your heart rate and shares it with the Apple Health app. The Heart Rate node of your Wellsmith care plan is designed only for use with single measurements from a blood pressure monitor while at rest.

In order to resolve the issue, you will need to prevent the device that is regularly capturing your heart rate measurements from sharing them with the Apple Health app. To do so, please perform the following steps:

  1. Open the Health app.
  2. Select Sources.
  3. Select the app for the device that is regularly capturing your heart rate measurements.
  4. In the Allow [APP] To Write Data section, ensure that the toggle for Heart Rate is in the "Off" position as denoted in green.
