ABSTRACT:
This technology will allow his doctor to
receive regular updates about his heart rhythms
and to be alerted when something is wrong.
Each night patients get settled and the implant
uploads information about their heart to a
transmitter. The data is then beamed to a
computer, which processes the information and
sends it to the cardiologist, via the internet, text
message or fax.
Cardiac patients can now be mobile and at the
same time under observation. A new wireless
device allows doctors to diagnose and more
effectively treat heart patients at earlier stages
by receiving electrocardiogram (ECG) data
remotely via mobile networks.
In this paper we covered architectureof device
and different methodsfor monitoring of heart
i..e mobile monitoring through blue
tooth,Ericsson method ,Cardionet and
Biotronik’s methods are mentioned and ECG
via Mobile Networks is explained.
HISTORY:
Developed by a Swedish company
called kiwok, the body kom system has been
made available to doctors and hospitals in
Sweden and Norway and is expected to arrive
in India by jan 2008.As Linder says: "With this
mobility factor you can save so many resources
without the doctor or nurse having to be there
for instruction and support while the patientsstill feel cared for."However, replacing the
doctor's bedside manner with technology may
not be the best medicine for some patients.
Working with the customers, Linder says, is
the best way to strike that balance. "It's about
finding the right level between saving money
and resources, and ensuring the patients feelsecure. But one thing is for certain: hospitals
need to send more patients home."
MOBILE MONITORING FOR
ARCHITECTURE:
GSM NETWORK:
• The global system for mobile
communications is the most popular

.
SERVER:
• A Server is a computer system
that provides services to other
computing systems called
Clients-over a network.
• It operates continuously on the
network and waits for requests
for services from other computers on the network.
SENSOR:
• The sensor which has the
responsibility to capture the
reliable vital sign data, has close
contact with the patients.
• To capture a patients vital signs
such as heart rate, and blood
oxygen saturation, a pulse
oximeter is needed.
MOBILE PHONE :
• The mobile phone is used as a
receiver,analyser,and further
transmitter of patients multiple vital
signs.
• Using Bluetooth, patients mobile
phone receives the vital signs,to
both analysis and memorize.

PROCEDURE FOR MONITORING OF
HEART PATIENTS THROUGH
MOBIILE:
Development of the system
A Wireless Health Outcomes Monitoring
System (WHOMS) prototype was designed and
developed in order to satisfy two main
objectives:
1. To allow patients to receive and self-report
structured questionnaires via either WAP or
web.
2. To allow the physician to examine data
reported on questionnaires through a graphicaland chromatic interface.
These objectives can be met in the following
ways
Fig: Scenarios representation.
• (Scenario 1) Periodical sending of
questionnaires to patients with mobile
handsets. The questionnaire shipment
uses a WAP/GPRS connection to senda "WAP Push Service Indication"
message to the patient's mobile phone.
The patient can see the questionnaire
on the phone display via the GPRS
connection.
• (Scenario 2) Questionnaire (10
symptoms questions in the prototype)completed by the patient. Using their
mobile phone, the patient completes
the questionnaire following the
directions presented on the display.
Questions are displayed one at a time
and a set of answers is presented in a
menu .The patient chooses the most
appropriate answer according to their
symptoms. Alternatively, for patients
who prefer to use personal computers,
a reserved online area can be accessed,where questionnaires can be compiled
or overall reports containing previous
answers can be displayed (note this
internet option for patients was not
trialled in the present study).
• (Scenario 3) Answer management.
Using a reserved online area, the
physician can examine patient's
symptoms according to their
questionnaire answers. The graphicaland chromatic representation allows
the doctor a quick and clear vision of
how the patient's symptoms are
evolving. A light
flashes by the
names of those
patients that
present seriously
modified
symptoms, so
that the physiciancan identify the
most significant
changes at once
and immediately
take the necessary action. The
parameters that determine the type of
change that will cause a flashing signal
can be customised by the physician
and are specific for each
questionnaire .

patient's answers to the questionnaire.
ECG VIA MOBILE:Electrocadiography is the generation of a
tracing or graph of electrical activity in the
heart. An electrocardiogram or
electrocardiograph (ECG or EKG) is the actual
tracing or graph of the heart's electrical activity
produced in electrocardiography
Fig: Heart rate(HR- 118) displayed on a
bedside monitor
The equipment consists of ECG electrodes, a
small control unit and a smart mobile
phone.ECG data is collected by the controlunit and a smart mobile phone. ECG data is
collected by the control unit and wirelessly
transferred to the mobile phone. The mobile
phone analyses the data if it deviates from
normal values it is forwarded to a decision
support system . The data is then transferred to
the health care providers system for analysis.An ECG can tell if the heart is beating
normally or detect heart disease or
problems with the electrical conduction
system of the heart. It records the rate and
regularity of heartbeats, can tell the size and
position of the chambers of the heart. An ECG
also can record signs of damage to the
heart and the effects drugs or devices
such as pacemakers and ICDs.
DIFFERENT METHODS FOR MOBILE MONITORING SYSTEM
FOR HEART PATIENTS:
MOBILE MONITORING THROUGH
CARDIOSMART:
Cardiosmart is intelligent and automatic to
allow continuous monitoring of a patients heart
condition.The stability and performance of the
technology was validated in tests last year, with
the coordinator wearing the personal terminal
when he attended meetings across Europe.
The core of this system is the analyzing of the
information collected from heart to mobile
phone and to focus on the
fine fluctuations of the R-R
intervals, which are
analyzed and processed by
using a particular algorithm
specially created for this purpose. The result is a
single parameter called
index µ, which expresses
the variability of the
heartbeats. Although a
large number of studies
have been made on HRV,
the µ index is calculated in
a completely new method, which allows
sensitive detection of HRV in an innovative
way.These computer-generated pictures greatlydifferent from one subject to another and vary

with the age of the patient and possible
abnormal conditions of the heart.
HEART MONITORING THROUGH
BLUETOOTH:
Bluetooth wireless technology is a short-range
communications system intended to replace the
cables connecting portable and/or fixedelectronic devices. The key features of
Bluetooth wireless technology are robustness,
low power, and low cost. Many features of the
core specification are optional, allowing
product differentiation.
The Bluetooth core system consists of an RF
transceiver, baseband, and protocol stack. The
system offers services that enable the
connection of devices and the exchange of avariety of data classes between these devices.
The prototype Bluetooth heart monitor
periodically records an electrocardiogram
(ECG) of the wearer’s heart and transmits
the information via radio frequency signals
to his or her modified mobile phone. If
signs of imminent heart failure are
detected, the phone analyzes the ECG
signal and sends a message via the SMS
text service to the nearest medical center.
ERICSSON MOBILIZING:
Ericsson is mobilizing patients and the
healthcare industry with a new complete
solution. The commercial launch of Ericsson
Mobile Monitoring in November will
introduce a wireless way to assess patient
wellbeing.
A recent heart attack victim, a young
asthmatic and a pregnant woman are
examples of those who can benefit from
Ericsson Mobile Monitoring for healthcare.With the
new system, body data such as heart rate,
respiration and oxygen saturation in the
blood can be assessed by a doctor via mobile
networks while the patient is at home or on
the move.
Based on individual
needs, the patient is fitted
with a mobile base unit
(MBU) – a number of
body sensors and a PDA
or smart phone. Body
data is measured and sent
via Bluetooth to the phone, which then
transmits the information
over GPRS and presents
it to the doctor in an
easy-to-use format.
Henrik Linder, solution
manager for healthcare at Ericsson
Enterprise, says mobile monitoring targets
the patient groups that put most pressure on
public healthcare resources.
"The simple cases are those where the patientgroups are enormous and the costs are
8/2/2019 Mobile Monitoring of Heart Patients
http://slidepdf.com/reader/full/mobile-monitoring-of-heart-patients 8/9
equally high," Linder says. "Primarily it's
cardiology, respiratory and diabetes patients
and those who are chronically ill." Pregnant
women and patients preparing for surgery
can also be assessed with the system.
Ericsson Mobile Monitoring can relay threedifferent types of body data in the same unit.
The first is streaming body data, such as heart
rate and respiration – objective data that can
be measured in real time.
The second is a measurement taken regularly,
such as blood-sugar levels, which can be sent
for assessment by the doctor as often as
necessary.
The third is patient diary data – subjective
information from patients about their general
wellbeing, quality of life and how they areresponding to prescribed drugs. This can also
be used as key information for the
pharmaceutical industry, helping to reduce
the time and cost of clinical trials for drugs.
CARDIONET:
CardioNet is the world's leading supplier of
mobile cardiac outpatient telemetry. CardioNet
provides the next-generation ambulatory
cardiac monitoring service with beat-to-beat,
real time analysis, automatic arrhythmia
detection and wireless ECG transmission.
CardioNet prides itself with helping clinicians
prevent morbidity, mortality and disability with
rapid diagnosis and treatment of patients with
cardiovascular disease.
BIOTRONIKS :
Biotronik's integration of remote data
transmission into the already well-establishedthree-chamber pacemaker Stratos expands the
options for congestive heart failure therapy.
"Home Monitoring is increasingly proving to
be a hope for the affected patients - as well as
an important factor of therapy management and
cost reduction in health care. We see ourselves
as a pioneer of this progressive technology. In
the not too distant future, it will be the standard
in cardiac resynchronization therapy," remarks
Dr. Werner Braun, Managing Director of
Biotronik, and he adds: "Shortly after welaunched the Kronos LV-T, the worldwide first
CRT ICD with Home Monitoring, we have
now taken an important step towards
completing our portfolio in this area."
Via Biotronik Home Monitoring, the Stratos
LV-T transmits important data about heart rate
and patient activity, as well as parameters used
for early detection of atrial fibrillation. The
Stratos LV-T uses three independent channels
to synchronize the activity of the heart
chambers - and significantly improves the patient's hemodynamics. As a unique CRT
system, the implant also offers three pacing
algorithms for the prevention of atrial
fibrillation, which is a common co-morbidity
of heart failure.
The Stratos LV-T is scheduled for market
release in the first quarter of this year. The
implant will be included in the Home Care
study, just as the Kronos LV-T is now. The
objective of this project is to establish the
parameters transmitted by Home Monitoring as
risk predictors and subsequently prove a
decrease of the hospitalization rate."
OXIMETER:
It is device
to observe
the
heartbeat.Oximeter
earpiece and mobile feedback.It is a
Continuous, untethered monitoring, coupled
with mobile feedback helps cardiovascular
patients modulate exertion and benefit from
exercise.
ALIVE HEART MONITOR:
The Alive Heart Monitor is awireless health monitoring
8/2/2019 Mobile Monitoring of Heart Patients
http://slidepdf.com/reader/full/mobile-monitoring-of-heart-patients 9/9
system for screening, diagnosis and
management of chronic diseases, and for
consumer health and fitness. Applications
include the management of atrial fibrillation
and heart failure, cardiac rehabilitation and
fitness monitoring. Designed for use in the doctor’s office, home
or gym, the monitor uses wireless Bluetooth
and mobile phone networks to immediately
transmit ECG and accelerometer data to a
computer, PDA, or central monitoring centre. It
features the latest generation of Bluetooth
wireless technology and new electrode
technology for optimum signal quality.
The Alive Heart Monitor can be used for
remote real time monitoring of exercise programs via the internet. Using the Alive
Heart Monitor, a GPS and mobile phone
carried by the person exercising, the program
supervisor or coach can remotely monitor the
exact position, speed, position, ECG and heart
rate in real time. For cardiac rehabilitation
programs, and for training programs for elite
athletes this provides real time feedback on the
intensity and performance, allowing
optimisation of the programs for maximum
benefit and safety.
ALIVE ECG :
The AliveECG software connects to the AliveHeart Monitor over a wireless Bluetooth
connection. It can be used to monitor a patient's
ECG, heart rate, activity, anddevice status, and
to record this data for later review.
ADVANTAGES:
The system benefits patients and healthcare
providers alike. While providing relief for
those who would normally have to endure long
periods of hospitalization, it frees up essential
healthcare resources that can be used more
effectively elsewhere.
CONCLUSION: Mobile health monitoring is
developed to track vital health sign, helping
to limit a patient’s health risk, reduce thenumber of clinical visits and capture more
accurate information.
