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

standard for mobile phones in the

world.

• GSM ability of being present in

every where and several places at

onetime

• It is made easy for international

communications between mobile

phone operators.



.

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.

ALTERNATIVE DESIGN THROUGH

SMS SERVICE:



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 .

example.

The physician can monitor all patients in a

schematic way. A flashing light allows the

physician to identify patients in which there

has been significant change.

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



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



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.
