The NUVANT Mobile Cardiac Telemetry (MCT) System is a wearable, wireless arrhythmia detection system that is used to aid clinicians in diagnosing
suspected cardiac arrhythmias. It consists primarily of the PiiX® wearable
monitoring device, the zLink® portable data transmission device and a Patient
Trigger Magnet to enable on-demand collection of ECGs (recordings of heart
rhythm). In combination with interpretation services provided by the Corventis
Monitoring Center, as well as secure online review of data (for prescribing physicians only), NUVANT MCT enables patient- and physician-friendly arrhythmia
detection for up to 30 days at a time.
How NUVANT MCT Works
Once activated, the wearable PiiX sensor continuously monitors the heart and
automatically collects ECGs when rhythm abnormalities are detected. Patients
can also drive collection of ECGs when they experience cardiac symptoms by
using the Patient Trigger Magnet. Data are automatically transmitted from the
PiiX to the zLink, which then automatically transmits the data to the Corventis
Monitoring Center. Certified cardiographic technicians at the Corventis
Monitoring Center review received data and document symptoms reported
by patients. Clinical reports, prepared by the Corventis Monitoring Center,
are delivered and made available at www.corventis.com to provide data to
prescribing physicians for the diagnosis and identification of various clinical
conditions, events and/or trends. Prescribing physicians may also be contacted
by the Corventis Monitoring Center directly when arrhythmias that meet predefined criteria are detected.
IMPORTANT:
• The NUVANT MCT System is not intended to be an alarm or to
alert patients or physicians, and will not summon emergency
response in the event help is needed.
• The NUVANT MCT System is not intended to replace direct communication with healthcare providers.
• Data provided by the system should be used by physicians along
with all other clinical findings and exams to come to a diagnosis.
• Patients should talk to their healthcare provider immediately if
there are any concerns or if their condition changes.

Using NUVANT MCT during the Monitoring Period
What to do when you feel cardiac symptoms
Use the Patient Trigger Magnet whenever you feel cardiac symptoms. It will
direct the PiiX to collect a record of your heart rhythm (ie, ECG), which will
then be automatically transmitted to your zLink and then automatically transmitted to the Corventis Monitoring Center for review by Corventis technicians.
This information will then be provided to your physician.
• Position the Patient Trigger Magnet at one end of the PiiX and move it
lengthwise, once, across the surface and towards the opposite end (for
example, as seen in the diagram)
• The Patient Trigger Magnet can be used over light clothing (for example,
a shirt or light sweater)
• Carry the Patient Trigger Magnet with you at all times (taking care not to
come into contact with credit cards)
• •Do not place the Patient Trigger Magnet in a shirt pocket or on a neck-
lace, as that might cause unnecessary ECG collection
IMPORTANT: You may be contacted by a technician from the Corventis
Monitoring Center to discuss symptoms when the Patient Trigger Magnet is used. When you experience any symptoms, please make note of
the following to discuss with a technician:
• Type of symptoms
• Time of symptoms
• Duration of symptoms
• What you were doing
How to use the zLink
The zLink should be kept within 30 feet (9 meters) of you at all times to allow
transmission of data from the PiiX to the zLink
• During the day, carry the zLink with you using the zLink Holster
• At night, keep the zLink close to you while you sleep (for example, on a
nightstand)
The zLink should be kept ON at all times to allow transmission of data from
the PiiX to the zLink
• The zLink may be turned ON and OFF manually by pressing and holding
the Power button for several seconds. However, please keep the zLink
turned on at all times to ensure transmission

to document symptoms and wear the PiiX. All of your data will be
stored on the PiiX and sent to the zLink when you are again within
range or when the zLink is turned back on.
How to charge the zLink
• Charge the zLink daily, (for example, every night while you sleep)
• The zLink may take up to 6 hours to fully charge
• With an adequate charge, the zLink can be used for up to 12 hours
before needing to be recharged
• The Linked, Cell and Send lights on the zLink are utilized by Corventis
Customer Service for troubleshooting. Refer to these lights only if asked
by a Corventis Customer Service representative
IMPORTANT: If the battery on the zLink runs out, you can continue to
use the Patient Trigger Magnet to document symptoms and wear the
PiiX. All of your data will be stored on the PiiX and transmitted once
the zLink is charged.
When to remove or replace the PiiX
Each PiiX device is designed to operate with normal wear and tear over the
course of use for up to 7.5 days. The PiiX is also water resistant. You can
keep wearing the PiiX while you shower, but do not submerge it in water (for
example, in a bath or hot tub).
Depending on the length of your prescription, you may need to wear more
than one PiiX. As seen in the diagram below, the PiiX display will let you
know when it should be removed.
• If you see a single blinking green
light within the filled circle symbol,
this means the PiiX is working
properly. You should continue to
wear the device.
• If you also see two red lights
within the circle with a crossed
line symbol, you should remove
and replace the device with a
new PiiX (unless your monitoring
period is over).
IMPORTANT: Each PiiX device should be worn continuously until the
two red lights behind the circle with the crossed line are seen.
This may take up to 7.5 days, but could be less. Once it has been
removed, do not reapply the PiiX as this will affect monitoring (ie, it is
meant for one-time use only). Please call Corventis Customer Service
at 1-877-247-PIIX (7449) if you have any questions about when to
remove the PiiX.

Arrhythmia Detection Algorithms and Automatic ECG Collection
In addition to patient-driven collection of ECGs using the Patient Trigger Magnet, the NUVANT MCT system also uses proprietary algorithms based on rate,
rhythm and morphology to continuously analyze rhythm abnormalities and
to initiate automatic ECG collection. ECGs are automatically collected upon
detection of the following conditions:
• Heart Rate >= 130 bpm
• Heart Rate <= 40 bpm
• Pause >= 3 seconds
• Atrial Fibrillation
• Ventricular Tachycardia/Ventricular Fibrillation
12
NUVANT
™
MCT Instructions for Use
ENGLISH
For example, the detection algorithm of the NUVANT MCT System detects the
peak of each R-wave and calculates the interval between successive R-waves.
The RR intervals are then used to calculate beat-to-beat heart rate values and
to initiate collection of ECGs. RR intervals are also aggregated into 5-minute
and 24-hour averages to summarize patient heart rate over the monitoring
period. For Pause detection, the algorithm monitors the time between successive R-wave peaks. A pause trigger is activated if an internal timer advances to
3 seconds without R-wave detection.
In order to provide relevant, exception-based arrhythmia reporting, the NUVANT
MCT System’s proprietary ECG analysis algorithms proactively manage redundant
reporting of ECGs for a select set of arrhythmias when persistently detected:
• Tachycardias with heart rate >= 130bpm and < 165bpm
• Bradycardias with heart rate >= 30bpm and < 40bpm
• Atrial Fibrillation
• Ventricular Tachycardia < 165bpm
For these arrhythmias, the PiiX algorithm detection sensitivity and positive
predictive value results, which are obtained from the respective databases in
strict accordance with EC-57* and with 0% downtime, are as follows:
Test Rhythm Name
Sensitivity
(%)*
Positive

* as measured by EC-57 standards testing on 10/25/2011
Redundant reporting of ECGs for this select set of arrhythmias is managed
as follows:
• The PiiX will report no more than two (2) ECGs for each of these
arrhythmias each hour
• The PiiX will wait ten (10) minutes before allowing a subsequent ECG to
be reported for each of these arrhythmias
Note: a) ECGs are reported for all Tachycardias with heart rate >= 165bpm,
all Bradycardias with heart rate < 30bpm and all Pauses >= 3 seconds; b)
The PiiX keeps a complete count of all arrhythmias that are detected; c)
Supplemental ECGs are also reported i) every six (6) hours for prolonged Atrial
Fibrillation episodes and ii) every twenty-four (24) hours, irrespective of the
presence of an arrhythmia
zLink Maintenance

Frequently Asked Questions
What is a PiiX?
A PiiX is a patient-worn medical device designed to comfortably adhere to the
skin. The device contains sensors that collect your ECG waveform (a tool for
analyzing the activity of your heart).
How long will my PiiX last?
Each PiiX device is designed to last up to 7.5 days (unless the memory fills up
beforehand). However, inappropriate PiiX application, or removal and reapplication of the PiiX during use, will affect monitoring. If this happens, you may
be required to use another PiiX.
What information is transmitted to my physician?
Your heart activity is monitored 24 hours a day, 7 days a week. Any unusual
heart activity is recorded, and transmitted for review to your physician.
What do I do when I feel symptoms?
Whenever symptoms occur, trigger the PiiX to record your heart activity by using the Patient Trigger Magnet (provided). Swipe the magnet along the entire
length of the PiiX, once, at a uniform rate. An ECG will be collected by the
PiiX, transmitted to the zLink and then transmitted to the Corventis Monitoring Center for review and delivery to your physician.
How can I report my symptoms?
Technicians from Corventis will occasionally call you to discuss your symptoms.
Please make note of the type of symptoms, the duration of symptoms, when
they happened and what you were doing so it can be discussed with a technician.
Should I keep the Patient Trigger Magnet with me at all times?
Yes, you should always carry the Patient Trigger Magnet with you. Please keep
the Patient Trigger Magnet away from your credit cards or identity cards as
the magnet may erase them. Also, please do not place the Patient Trigger
Magnet in a shirt pocket or on a necklace, as that might cause unnecessary
ECG collection.
Can I take a shower while wearing my PiiX?
Yes, the PiiX is water resistant so you can shower while wearing it. However,
do NOT submerge PiiX in water by swimming or sitting in a hot tub. In addition, avoid excessive rubbing of the PiiX during showering.
Should I carry the zLink with me when I travel?
Yes, take zLink with you at all times. zLink will remain charged for up to 12
hours. If you plan to be away for longer than 12 hours, take the zLink charger
with you.
