What is a physiological signal simulator?◦ Reproduces physiological signals◦ Compare healthy versus unhealthy signals◦ Analyse disease characteristics◦ Manipulate signals◦ Communicate with devices such as phones and
monitors
Applications?◦ Medical training & education◦ Research & technology development◦ Sports & fitness
Introduction
Low cost Easy to access Select, reproduce and analyse signals Intuitive Provide feedback Output data
Aims

Progress to Date
Concepts of the ECG Records electrical
activity of the heart In resting state
muscles are negatively charged
P-QRS-T Complex Changes occur with
heart disease Reference points
Depolarisation Repolarisation
Selection of Signals
Tasks Completed Physionet File
Read data from Physionet files
Format files to only include relevant data
Save to format readable by LabVIEW
JKI State Machine String based Queue State Machine Allow user actions to determine next state
Flowchart to Date
