USING YOUR ZIO AT
With the Zio AT, you can sleep,
shower and go through your
normal daily activities.
Your patch needs time to fully stick to your
skin. For the rst 24 hours after application,
please avoid:
• Showering or bathing
• Any activity that will cause sweating
After 24 hours, you can go back to these
normal activities, including moderate
exercise.
USING ZIO
Remember:
1Press the button on your patch any time you feel a symptom, then log your
symptom in the myZio app. You may also
enter your symptoms on myzio.com or in
the Button Press Log on the ip side of this
manual
2Keep the gateway nearby
as much as possible
including when
you’re on the move.
Keep in mind that
data sending
may be stalled if the
gateway is more
than 10 feet from
the patch. Once
back in range, data
transfer will resume
and no data will
be lost.
3
The patch and
gateway will not ash or make noise if
they are working properly. A ashing patch
or gateway does NOT signal a problem with
your heart. One of the devices may have
lost connection. Review the Troubleshooting
section or call 1.888.693.2401 for assistance.

USING ZIO
Additional Tips:
You may start to feel itchy under the
patch, but please keep the patch on
unless the itching becomes severe.
If the patch starts to peel o, press
evenly on the wings of the patch for
3 to 5 minutes.
Too much sweating can cause the
patch to loosen or fall o.
Protect the gateway from water at all
times. Do not submerge the patch in
water. Keep showers brief and avoid
swimming or hot tubs.
Try not to place the gateway within
six feet of transmitting devices, such
as wireless routers, baby monitors
and TV senders/ transmitters. These
devices may cause interference
between the patch and the gateway.
Use myZio to enter your symptoms and
check symptomatic transmissions sent
from your gateway. You’ll also have access
to instructions and support videos.
Note: transmissions may take time to
appear online.

FREQUENTLY ASKED
QUESTIONS (FAQS)
The Zio® AT Monitoring System
What is the patch doing?
The patch is recording every heartbeat.
Your doctor will use the heart rhythm
data from the patch to determine the
right course of action.
What is the gateway doing?
The gateway wirelessly sends heart rhythm
data recorded by your patch to iRhythm.
iRhythm analyzes the data and provides a
report to your doctor.
How do I know the patch and the gateway
are working?
If you saw green ashes after turning on
the patch and gateway, both devices are
working. When they are working normally,
the patch and gateway do not ash or
make noise.
Do I need to do anything after pressing the
patch button to send heart rhythm data
wirelessly?
Do your best to keep the gateway in front of
you and within 10 feet as much as possible.
The gateway should also be kept in a place
with good cellular connection.

FAQs
Can I carry the gateway in a purse, bag or
pocket?
Yes. However, the gateway will need to be in
front of your body and within 10 feet of the
patch. You may also use the provided belt clip to
carry the gateway.
What can aect wireless connection between
the patch and the gateway?
Wireless devices that use 2.4 GHz signals
such as baby monitors, TV senders,
and wireless routers can interrupt
communication between the patch and
gateway if used within 6 feet. Objects
placed inside the gateway can also cause
communication problems.
Your Activities
Can I exercise while wearing the patch?
Yes, you may exercise moderately, but
excessive sweating may shorten wear time.
Can I shower with the patch on?
After 24 hours following application, you
may take brief showers. Try to keep your
back faced toward the shower. Hold the
patch down while towel drying to prevent
accidental removal. Avoid getting the
gateway wet.
Can I take a bath?
Yes, but keep the patch above water. Keep
the gateway away from all water.
Can I go into a pool or a hot tub?
No. The patch should not be submerged
under water. Keep the gateway away from
all water.
Can I travel with the patch on?
Yes. If questioned during airport security
screening, show the statement in the
Traveling section. Note that the gateway
will not have cellular connection outside
the United States.
Can I y with the gateway?
Yes, the gateway should be placed in
“airplane mode.” See Traveling section.
What activities should I avoid?
Avoid activities that cause heavy sweating.
Sweat can cause the patch to slide,
become loose or fall o. Activities that
may submerge the patch in water should
also be avoided.

FAQs
Recording Symptoms
What should I do if I feel a symptom?
First, press the button on your patch. Then
enter your symptoms in the myZio app or in
myzio.com. You may also ll out a page of
the Button Press Log in this manual. Please
choose only one option for recording your
symptoms.
What if I forget to press the button when I feel
a symptom?
The patch will still record your heartbeat and
the gateway will send any information that is
important for your doctor to know.
What if I press the button but forget to write
down the symptom?
Recording your symptoms and activity gives
your physician additional information about
what may have caused the symptom. While
this is useful, it is most important to press
the button.
What if I press the patch button while the
gateway is not within 10 feet and in line of
sight of the patch?
The patch will store the data until the gateway is
in range, then the data will be sent.
What happens if I press the patch button while
the gateway doesn’t have cell signal?
The gateway will store the data until it has
cell signal, then the data will be sent.
The Patch
What should I do if the patch peels or lifts at
the edges?
Press evenly on the wings of the patch for
3 to 5 minutes to re-stick.
What should I do if the patch falls o?
Call Customer Service at 1.888.693.2401.
I think I see blood under my patch. What
should I do?
Call Customer Service at 1.888.693.2401.
It is probably due to a small shaving cut
when the patch was applied to your chest.
Is it normal for the Zio® AT patch wings to
become cloudy?
Yes. The patch may move slightly from its
original position. A blue gel may be seen
under the wings of the patch.
Is it normal for the patch to move slightly
from its original position?
Yes. The patch may move slightly from its
original position. A blue gel may be seen
under the wings of the patch.

FAQs
Is it normal to experience skin irritation or
itchiness in the area of the patch?
Many patients do not experience skin irritation or
itchiness. However, some patients report minor
skin irritation and/or itching while wearing the
patch. If the irritation or itching is severe or hives
or blisters develop, remove the patch and then
call Customer Service at 1.888.693.2401.
Flashing Lights
Will the gateway show any lights or make any
sounds?
No. As long as it is able to send data, the
gateway will not ash or make noise.
What if the patch ashes orange while I am
wearing it?
If you see the patch ashing orange, this
does not mean there is a problem with your
heart; it just means that the patch is not
well attached. Press evenly on the wings of
the patch for 3 to 5 minutes. If the ashing
continues or comes back, call Customer
Service at 1.888.693.2401
What should I do if my gateway is ashing
orange?
If you see the gateway ashing orange, this
does not mean there is a problem with your
heart; it just means that the patch cannot
send information wirelessly. Turn to
Troubleshooting or call Customer Service at
1.888.693.2401.
End of the Wear Period
How long am I supposed to wear the patch?
Wear the patch for as long as your doctor
prescribed but no longer than 14 days. NOTE:
Each person’s wear experience is dierent
and actual wear time may be shorter than
prescribed.
I have removed the Patch and it is ashing
orange. Is this okay?
The patch may ash orange after removal.
It is okay to mail the device while it is
ashing. Turn to Patch Removal for return
instructions.
