To evaluate cardio vascular risk in the patient with coronary heart

disease.

SOFTWARE:

Heart development program software.

Cardio vascular _risk _2software(doctorslongue.com)

PROCEDURE:

Enter the data in to the form.

Then click compute.

Display the percentage of risk.

THEORY:

CORONARY HEART DISEASE

Coronary heart disease is the narrowing or blockage of the coronary arteries,

usually caused by atherosclerosis. Atherosclerosis is the buildup of cholesterol and

fatty deposits(called plaques) on the inner walls of the arteries. These plaques can

restrict blood flow to the heart muscle by physically clogging the artery or by

causing abnormal artery tone and function.

Without an adequate blood supply , the heart becomes starved of oxygen and

the vital nutrients it needs to work properly. This can cause chest pain called

angina. If the energy demands of the heart become much greater than its blood

supply , a heart attack may occur.

To determine the inpatient and outpatient details.

SOFTWARE:

MYCIN- Hospital Management Software.

PROCEDURE:

Enter the details of the patients.

Save the details in the databases.

Generate the report.

Theory:

MYCIN is one of the most widely known medical expert system. It contains

number of rules developed by the physicians and surgeons. It is the program for

advising the physician and treating the bacterial infection of the blood. It was the

first large medical expert system that provides user the explanation and reasoning.

MYCIN conducts a question and answer dialogue such as name, age , sex,

infection area and the presence of specific symptoms relevant diagnosis of the

disease and then it recommends certain course of anti biotics. MYCIN never

compares the symptoms of two different patients.

To determine the Epilexia of blind patient by TEIRASIS.

HARDWARE:

Computer.

Printer.

Chart.

SOFTWARE:

TEIRASIS medical software.

Printer software.

THEORY:

TEIRESIAS recognizes that some of the knowledge required for the

knowledge base is inexact or rough and it succeeds in offering advice for its

correction. It also provides method for extracting the best performance out of an

expert system such as MYCIN.

TEIRESIAS's approach is to make use of the expert's ability to correct incorrect or

partially correct responses to common questions and then to focus the expert's

TEIRESIAS fixes bugs by

1) Stopping the performance program when the human expert identifies an

error;

2) Working backwards through the steps in the performance program that

led to the error until the bug is found;

3) Helping the expert fix the bug by modifying the knowledge base

EXP.NO: 3 EPILEXIA OF BLIND PATIENT

DATE: USING TEIRASIS MEDICAL SOFTWARE

TEIRESIAS's techniques for generating explanations are based upon two

assumptions

The two assumptions used are;

1) That a recapitulation of program actions can be an effective explanation

as long as the correct level of detail is given

2) That there is some shared framework for viewing the program's actions

that will make them understandable to the user.

PROCEDURE:

Take one option.

After selecting the condition enter data in the sheet.

After that some other table will displayed.

Then enter data into the next table.

Then we will obtain the result.

Then click compute.

Probability of disease will display.

OUTPUT:

RESULT:

Thus the Epilexia of a blind person was simulated & analysed successfully

by using TERASIS medical software.
