Monitoring Heart Health Remotely
through Facial Scans
Heart rate variability and the standard deviation of NN intervals
are two measures that are commonly used to assess heart health.
HRV is a measure of the variation in time between
heartbeats, while SDNN is a measure of the overall
variability in heart rate.
Both measures can be used to assess the health of
the cardiovascular system and to identify risk factors
for cardiovascular disease.
HRV is thought to be a good indicator of
the autonomic nervous system function,
which controls involuntary bodily
functions such as heart rate, blood
pressure, and respiration.
The ANS has two divisions: the
sympathetic nervous system, which
promotes arousal and stress response,
and the parasympathetic nervous
system, which promotes relaxation and
SDNN is thought to be a good indicator of overall heart
It is a measure of the variability in heart
rate, which can be affected by factors
such as stress, physical activity,
medications, and underlying medical
Elevated levels of SDNN have been
associated with increased risk of
HRV and SDNN has traditionally been measured using a variety of
methods, including electrocardiography, Holter monitoring, and
ambulatory blood pressure monitoring.
