Introduction

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

Nation’s leading killer for both men and women

This disease kills all racial and ethnic groups

About 1 million American die of CVD each 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 MeasurementSignals from two leads are

connected between two point of the body

Electrical voltage observed between the electrodes is given by the dot product of the two vectors

Modern standard ECG – uses more electrode connection points

Heart Rate

In normal sinus rhythm, a resting heart rate of below 60 bpm is called bradycardia and a rate of above 90 bpm is called tachycardia

In this diagnosis, I calibrated Normal Heart Rate = 100 and more than that results in some form of Cardiovascular heart disease

VB.NetApp SQL

ServerDatabase

The Application(VB.Net)

Major Functions in the Application

CreateDatabase() Create Table()

CreateProcedure()

CreateView()

PopulateTable()

DisplayData()

CreateDatabase() Using SQL statements you can create database objects programmatically Private Sub bntCreateDatabase_Click(ByVal sender As

System.Object, ByVal e As System.EventArgs) Handles bntCreateDatabase.Click

If bntCreateTable.Enabled Then Dim dr As DialogResult = MessageBox.Show If dr = DialogResult.Yes Then ResetUI() CreateTable() End If Else CreateTable() End If End Sub This function creates a database in the form of a table.

Function CreateTable ( )

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.

CreateTable Cont’ Private Sub bntCreateTable_Click(ByVal sender As System.Object, ByVal e As

System.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 aspect

in 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 = _ "USE Ecg" & vbCrLf & _ "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 Procedure is DROPPED, then re-create Procedure cmd.CommandText = _ "CREATE PROCEDURE AddDiagnostic AS" & vbCrLf

& _ "INSERT INTO NW_Diagnostic" & vbCrLf & _"(DiagnosisID,Temperature,Humi,SignalVoltage,Enviro,Ba

tteryVoltage,Name) “ "SELECT

DiagnosisID,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 the entities or semantic objects defined in the data model

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

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

This is most likely done via a data entry form, but applications 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 = _ "USE Ecg" & vbCrLf & _ "IF EXISTS (" & _ "SELECT * " & _ "FROM Ecg.dbo.sysobjects " & _ "WHERE Name = 'GetDiagnostic' " & _ "AND TYPE = 'v')" & vbCrLf & _ "BEGIN" & vbCrLf & _ "DROP VIEW GetDiagnostic" & vbCrLf & _ "END"

CreateView cont’

Re-create ViewTry cmd.CommandText = _ "CREATE VIEW GetDiagnostic AS " & _ "SELECT * " & _ "FROM NW_Diagnostic" cmd.ExecuteNonQuery() northwindConnection.Close() bntPopulateTable.Enabled = True

PopulateData()

The PopulateData statement inserts rows into a table, nickname, or view, or the underlying tables

Inserting a row into a nickname inserts the row into the data source object to which the nickname refers. 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 operation on this view.

PopulateData cont’

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

Dim strSQL As String = "EXECUTE Ecg.dbo.AddDiagnostic" Try Dim cmd As New SqlCommand(strSQL,

northwindConnection) northwindConnection.Open() cmd.ExecuteNonQuery() northwindConnection.Close() bntDisplayData.Enabled = TrueEnd Try End Sub

Function Display Data ()

The function DisplayData is the end result of the above functions. Users want to see data being display as well as programmers. This function will display all data depending on which format is being used. In this application, the bntDisplayData will display data in the DataGrid.

DisplayData() cont’ Private Sub bntDisplayData_Click(ByVal sender As System.Object, ByVal e

As System.EventArgs) Handles bntDisplayData.Click If IsNothing(dgDiagnosis.DataSource) Then Dim strSQL As String = _ "USE Ecg" & vbCrLf & _ "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 Try End IfEnd Sub

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

SignalVoltage as string, Temperature as Integer, HeartRate as Integer, Systolic as Integer, Diastolic as Integer, Smoke as Boolean;

if ( heartRate > 100) then disease =”Highblood pressure”else if (systolic >130)disease= “Cardiovascular”else if (diastolic > 80)disease = “Coronary artery disease”elsedisease = “Normal sinus”End ifEnd

Generate FinalReportFinal reports is comprehensive for

the following reasons:ReliabilityCorrectnessHelp doctors to know the big picture:• Best-Case Performance• Average-Case Performance• Worst-Case Performance

Generate FinalReport cont’

The final report is mostly queries generated during the diagnosis phase. Example of the final report’s retrieval using Subquery:

SELECT Diagnosis.Name FROM 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): The standard e-mail protocol on the Internet and part of the TCP/IP protocol suite

SMTP defines the message format and the message transfer agent (MTA), which stores and forward the mail

SMTP was originally designed for only plain text (ASCII text), but MIME and other encoding methods enable executable programs and multimedia files to be attached to and transported with the email message.

Conclusion and Future Considerations

I have learnt a lot from this project and this will help me to go deep into database programming. After finishing this project, I highly recommend that the code for streaming signal voltage from the ECG to the database should have the same platform as the ECG Database and Report Generator. This will help to automate the streaming of data with alongside with the Database Report Generator.

The future continuation development of this project should include internet base programming and a function that can be connected to a phone device in other to send phone message to the doctor.
