  • A complete diagnosis cannot be made based on Vastvitalz alone, consult with your physician before making any medical decision, including altering your medication or treatment.
  • Vastvitalz does not detect or register all changes in heart rates, heart rhythms and heart waveform.
  • Interpretations made by Vastvitalz are potential findings, not a complete diagnosis of cardiac conditions. All interpretations should be reviewed by a medical professional for clinical decision making.
  • Do not perform measurements while driving or during physical activity.
  • Do not perform measurements when the camera lens is uncleaned or broken.
  • After PPG analysis, the app may incorrectly identify some conditions as unreadable. Please consult with your physician.

Vastvitalz is not intended to be used by all individuals:

  • Persons under the age of 18 years.
  • Persons with conditions causing tremors or the inability to hold their hand still for at least 60 seconds (e.g. Parkinson or dementia) as, in this case, the device cannot process an accurate measurement.
