overview
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
12 lead ecg
12 – Lead ECG
  • Diagnose heart arrhythmias
  • More comprehensive view of electrical activity
  • Electrode placement based on anatomical landmarks
training mannequin
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
existing ecg training devices
Existing ECG Training Devices
  • Expensive
  • Known electrode placement
    • Not determined by anatomical landmarks
    • Ineffective training for placement
ecg signal
ECG Signal
  • ECG signal generator
    • 12-lead signal
    • Various arrhythmias
  • Conductive mannequin surface
    • Ag-Ni woven mesh
    • Latex-carbon mix
  • ECG monitor
    • Standard electrodes
electrode placement feedback
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
future work
Future Work
  • Determine an appropriately conductive biomaterial to use for the skin
  • Construct circuit on the chest plate
  • Modify 12 – Lead ECG simulator
