2. Overview The 12 – Lead ECG: Uses and Electrode Placement
Training Mannequin Specifications
Existing ECG Training Mannequins
Design Alternatives
ECG Signal Generator
Electrode Placement Feedback
Future Work

3. 12 – Lead ECG Diagnose heart arrhythmias
More comprehensive view of electrical activity
Electrode placement based on anatomical landmarks

4. Training Mannequin Develop an adult mannequin for 12-lead ECG training
Mannequin should produce a variety of ECG signals
Students should place ECG electrodes on the chest using anatomical landmarks
Provide feedback about correct/incorrect placement

5. Existing ECG Training Devices
Expensive
Known electrode placement
Not determined by anatomical landmarks
Ineffective training for placement

6. ECG Signal ECG signal generator Conductive mannequin surface
12-lead signal
Various arrhythmias
Conductive mannequin surface
Ag-Ni woven mesh
Latex-carbon mix
ECG monitor
Standard electrodes

7. Electrode Placement Feedback
Design 1
Feedback circuit
12-lead capability
Separate placement feedback display
Electrode isolation
Anatomical landmarks
Design 2
LED marked placement
12- and 15-lead capability
Anatomical landmarks

9. Design Matrix Feedback Circuit LED Markers Durability (15) 7 9
Cost (10) 8
Client Preference (25) 10 21
Feasibility (30) 13 24
Ease of Use (20) 15 17
Total 53 79

10. Future Work
Determine an appropriately conductive biomaterial to use for the skin
Construct circuit on the chest plate
Modify 12 – Lead ECG simulator
