This V19 smart health band is in the same class as the i7E recently reviewed. Make sure you watch that one as well to get a broad understanding about new ways of monitoring hearth health. Much of this new technology is due to the expertly designed WoFit tethering app (which should be use as a model for all other tethering apps). This app has multiple tiers of information showing the exact data that underlies the presented conclusions. For example, one of the most amazing features of this band/app combination is special Lorenz Scatter Diagrams (scatter plots). In the background, starting at midnight, the V19 begins continuously assessing heart rate variability for placing little dots on an ever evolving scatter plot. It resets itself each night at midnight and does its testing throughout the night. A user doesn’t need to touch anything, just wear the band to bed. Later, when the data is synced with the app, the scatter plot is created. This happens night after night, and can be examined and studied in detail. It’s an extensive X-Y graph of HRV values plotted in a way that allows for irregularities to be instantly viewable.
NOTE: The 2019 V19 smart band acquires ECG using only one lead! How is that possible? Read this:

Important Notices for Heart Monitoring Devices –
BIOMETRIC MEASUREMENT WARNING: This device claims to produce and evaluate heart wave ECG data. The accuracy of the readings HAVE NOT BEEN VERIFIED and MAY NOT BE ACCURATE. As such, you are advised to proceed with caution and to *NOT* rely upon readings from this or any similar devices for making decisions regarding your medical condition or health. Fitness/Health watches/bands offering biometric measurements such as heart rate, Blood Pressure, blood oxygen, fatigue, breath rate, etc., should be considered supplemental to seeking true and accurate readings taken under optimal conditions by trained professionals using accurate, calibrated equipment. If you feel concerned about your health, do not self-diagnose, especially from using inexpensive, uncalibrated non-medical wearable devices such as this one. Seek proper medical advice. Enjoy your new toy, but remember, it is a toy.
