JAMES PARK: Hello, everyone.
I'm James Park, cofounder of Fitbit.
I joined Google just a little over a year ago,
and it's great to be here today to share more about how Fitbit
continues to help people on their health and wellness
journey.
More than 15 years ago, we created Fitbit with a vision
to help make everyone in the world healthier.
Since then, we pioneered a new category of wearable technology
that makes health more accessible, fun,
and achievable.
We do this through our devices and services,
and by working with health plans and employers
to make health care more accessible and affordable
for everyone.
We know that being healthy is far more than just activity.
It's about holistic health and how it all fits together.
For example, tracking nutrition, helping with a better night's
sleep, or managing stress.
Our Fitbit platform makes managing overall health fun
and motivating.
Behind our wearables are many technological innovations
that continue to push the limits of what wearable sensors can do
to make the invisible visible.
For instance, Fitbit was one of the first to support
continuous wrist-based heart rate tracking.
We were also one of the first to bring sleep tracking
to wearable devices with a multifaceted view that included
measuring stages of sleep and offering insights on sleep
quality.
We were the first to bring an Electrodermal Activity, or EDA,
sensor to wearables, measuring hand perspiration
to measure how your body is responding to stress.
We've also made metrics like oxygen saturation, skin
temperature, and breathing rate more accessible,
putting users effortlessly in control
of their health and wellness.
Among the areas where we believe wearables can have
the most impact is heart health.
Heart rate is a foundational metric for general health
and well-being.
And it's also been a core offering for Fitbit users
from the early days.
PPG optical sensors are able to measure the tiny fluctuations
of blood that happen under the skin with each heartbeat.
We use these sensors in our wearables
to measure blood volume changes to track heart rate
and variability during a workout or while sleeping.
In recent years, with an increased focus
on supporting chronic conditions,
we tested and launched our first FDA-cleared ECG,
or Electrocardiogram, app that allows people
to assess their heart rhythm for signs of Atrial Fibrillation,
or AFib.
a heart condition that affects nearly 33.5 million people
globally.
AFib can be difficult to detect outside a hospital or clinic,
as episodes can be sporadic and asymptomatic.
Some studies suggest that as many as 25%
of people who have an AFib-related stroke find out
they have AFib only after a stroke has occurred.
Because it can be so hard to detect,
being able to more continuously look for signs of AFib
is essential, including at night when the body is at rest.
That's why, in 2020, we launched the Fitbit Heart
Study, a clinical study directed by doctors at Harvard
involving nearly half a million Fitbit users to test our PPG
AFib algorithm, which looks at heart rate data passively
and can alert users to a sign of any irregular heart rhythm.
The study results presented at the most recent American Heart
Association meeting showed the algorithm accurately identified
undiagnosed AFib 98% of the time.
We've submitted our algorithm to the FDA for review.
This is one of the many ways we're
continuing to make health even more accessible to more
people around the world.
