  1. 12 Lead ECG Trainer Cali Roen, Laura Bagley, Tony Schuler, Amy Weaver Client: Dr. Patricia Padgen, Dept. of Emergency Medical Services Advisor: Prof. Tom Yen, Dept. of Biomedical Engineering BME 400 October 17, 2008

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

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

  8. Design Matrix

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