Introduction

Cardiovascular disease (CVD),principally heart disease and stroke.

Nation¶s leading killer for both menand women

This disease kills all racial and ethnicgroups

About 1 million American die of CVDeach year



Introduction cont¶

According to American Heart

Association, one person dies

every 30 seconds which is over 2,600 deaths in every single day.

Victims between 35-64 years of

ageAbout 62 million Americans have

some form of cardiovascular

disease



ECG Measurement

Signals from two leads are

connected between two point of the

body

Electrical voltage observed betweenthe electrodes is given by the dot

product of the two vectors

Modern standard ECG ± uses moreelectrode connection points



Heart R ate

In normal sinus rhythm, aresting heart rate of below 60

bpm is called bradycardia and a

rate of above 90 bpm is called

tachycardia

In this diagnosis, I calibratedNormal Heart Rate = 100 and

more than that results in some

form of Cardiovascular heart

The Application(VB.Net)



Major Functions in the Application

CreateDatabase()

Create Table()

CreateProcedure()

CreateView()

PopulateTable()DisplayData()



CreateDatabase() Using SQL statements you can cr eate database o bjects progr ammatically

Pr ivate Sub bntCreateDatabase_Click(ByVal sender AsSystem.Object, ByVal e As System.EventAr gs) HandlesbntCreateDatabase.Click

If bntCreateTable.Enabled Then

Dim dr As DialogResult = MessageBox.ShowIf dr = DialogResult.Yes Then

ResetUI()

CreateTable()

End If

Else

CreateTable()

End If

End Sub

This function cr eates a database in the for m of a table.



Function Cr eateTable ( )

The CREATE TABLE statement

defines a table. The definition

must include its name and all the

attributes of its columns. The

definition can include other

attributes of the table, such as

its primary key or check

constraints.



Cr eateTable Cont¶

Private Sub bntCreateTable_Click(ByVal sender As System.Object, ByVal e AsSystem.EventArgs) Handles bntCreateTable.Click

Dim strSQL As String = _

"USE Ecg" & vbCrLf & _

"IF EXISTS (" & _

"SELECT * " & _

"FROM Ecg.dbo.sysobjects " & _

"WHERE Name = 'NW_Diagnostic' " & _

"AND TYPE = 'u')" & vbCrLf & _

"BEGIN" & vbCrLf & _

"DROP TABLE Ecg.dbo.NW_Diagnostic" & vbCrLf & _

"END" & vbCrLf & _

"CREATE TABLE NW_Diagnostic (" & _

"DiagnosisID Int NOT NULL," & _

"Temperature NVarChar(10) NOT NULL," & _

"Humi NVarChar(10) NOT NULL," & _

"SignalVoltage NVarChar(10) NOT NULL," & _"Enviro NVarChar (10) NOT NULL, " & _

"BatteryVoltage NVarChar (10) NOT NULL, " & _

"Name NVarChar(10) NOT NULL, " & _

"CONSTRAINT [PK_DiagnosisID] PRIMARY KEY CLUSTERED" & _

"(DiagnosisID))"



CreateProcedure( )

Stored procedures are important aspectin all database programs

VB.NET applications are no exceptions to

this rule. Stored procedures enable users change

the business logic without actually

tinkering with the application.



CreateProcedure() cont¶

First ,you have to DROP Procedure if it existsDim strSQL As String = _


"IF EXISTS (" & _

"SELECT * " & _"FROM Ecg.dbo.sysobjects " & _

"WHERE Name = 'AddDiagnostic' " & _

"AND TYPE = 'p')" & vbCrLf & _

"BEGIN" & vbCrLf & _"DROP PROCEDURE AddDiagnostic" & vbCrLf & _

"END"



CreateProcedure( ) cont¶

Once the Procedur e is DR OPPED, then r e-cr eate Procedur e cmd.CommandText = _

"CREATE PROCEDURE AddDiagnostic AS" & vbCrLf & _

"INSERT INTO NW_Diagnostic" & vbCrLf & _

"(DiagnosisID,Temperature,Humi,SignalVoltage,Enviro,BatteryVoltage,Name) ³

"SELECTDiagnosisID,Temperature,Humi,SignalVoltage,Enviro,BatteryVoltage,Name " & "FROM

Northwind.dbo.Diagnosis "cmd.ExecuteNonQuery()

northwindConnection.Close()

bntCreateView.Enabled = True



Function CreateView ()

A view is a structured list of items from theentities or semantic objects defined in the datamodel

A view instance is a view that is populated withdata for one entity or semantic object

To create a view instance, the application mustfirst obtain the new data values and relationships

This is most likely done via a data entry form, butapplications also receive data from other program and in other ways



Function CreateView () cont¶

DROP View if it exists

Private Sub bntCreateView_Click(ByVal sender As System.Object,ByVal e As System.EventArgs) Handles bntCreateView.Click

Dim northwindConnection As New SqlConnection(connectionString)Dim strSQL As String = _


"IF EXISTS (" & _

"SELECT * " & _

"FROM Ecg.dbo.sysobjects " & _

"WHERE Name = 'GetDiagnostic' " & _"AND TYPE = 'v')" & vbCrLf & _

"BEGIN" & vbCrLf & _

"DROP VIEW GetDiagnostic" & vbCrLf & _

"END"



Cr eateView cont¶

Re-create View

Try

cmd.CommandText = _

"CREATE VIEW GetDiagnostic AS " & _

"SELECT * " & _

"FROM NW_Diagnostic"

cmd.ExecuteNonQuery()


bntPopulateTable.Enabled = True



PopulateData()

The PopulateData statement inserts rows into a

table, nickname, or view, or the under lying tables

Inserting a row into a nickname inserts the row into the data source o bject to which the nickname

r ef er s. Inserting a row into a view also inserts the

row into the table on which the view is based, if

no INSTEAD OF TRIGGER is defined for the insert oper ation on this view.



PopulateData cont¶

Private Sub bntPopulateTable_Click(ByVal sender AsSystem.Object, ByVal e As System.EventArgs)Handles bntPopulateTable.Click

Dim strSQL As String = "EXECUTEEcg.dbo.AddDiagnostic"

Try

Dim cmd As New SqlCommand(strSQL,northwindConnection)

northwindConnection.Open()cmd.ExecuteNonQuery()


bntDisplayData.Enabled = True

End Try

End Sub



Function Dis play Data ()

The function Dis playData is the end r esult

of the above functions. User s want to see

data being dis play as well as progr ammer s. This function will dis play all data

de pending on which for mat is being used.

In this a pplication, t

he bntDi

s playData will dis play data in the DataGrid.



DisplayData() cont¶

Private Sub bntDisplayData_Click(ByVal sender As System.Object, ByVal eAs System.EventArgs) Handles bntDisplayData.Click

If IsNothing(dgDiagnosis.DataSource) Then

Dim strSQL As String = _


"SELECT * " & _

"FROM GetDiagnostic"

Try

Dim northwindConnection As New SqlConnection(connectionString)

Dim cmd As New SqlCommand(strSQL, northwindConnection)

Dim da As New SqlDataAdapter(cmd)

Dim dsDiagnostic As New DataSet

da.Fill(dsDiagnostic, "Diagnostic")

End TryEnd If

End Sub



ECG

Report Analyzer



ECG Diagnostic Analyzer

Diagnostic Analyzer uses algorithm to diagnose the patient¶s condition. For example:

SignalVoltage as string, Temperature as Integer, HeartRate asInteger, Systolic as Integer, Diastolic as Integer, Smoke asBoolean;

if ( heartRate > 100) thendisease =´ Highblood pressure´

else if

(systolic >130)

disease= ³ Cardiovascular ́

else if

(diastolic > 80)

disease = ³ Coronary artery disease´

else

disease = ³ Normal sinus´

End if

End



Gener ate FinalR e port

Final reports is comprehensive for the following reasons:

Reliability

CorrectnessHelp doctors to know the big picture:

Best-Case Performance

Average-Case Performance Worst-Case Performance



Generate FinalReport cont¶

The final report is mostly queries generatedduring the diagnosis phase. Example of thefinal report¶s retrieval using Subquery:

SELECT Diagnosis.NameFROM Diagnosis

WHERE Diagnosis.DiagnosisID IN

(SELECT History.Heredity

FROM History.Medication IN

(SELECT * FROM DiseaseOne));



Function EmailSender()

According to definition by [2], SMTP

(Simple Mail Transfer Protocol): Thestandard e-mail protocol on the Internetand part of the TCP/IP protocol suite

SMTP defines the message format and themessage transfer agent (MTA), whichstores and forward the mail

SMTP was originally designed for onlyplain text (ASCII text), but MIME and other encoding methods enable executable

programs and multimedia files to beattached to and transported with the emailmessage.

Conclusion and Future Considerations

I have learnt a lot from this project and this willhelp me to go deep into database programming.After finishing this project, I highly recommendthat the code for streaming signal voltage fromthe ECG to the database should have the sameplatform as the ECG Database and ReportGenerator. This will help to automate thestreaming of data with alongside with theDatabase Report Generator.

The future continuation development of thisproject should include internet baseprogramming and a function that can beconnected to a phone device in other to sendphone message to the doctor.
