Simulation design and research on forming principle of anthropometric ECG / 医疗卫生装备

Objective To vividly display the forming principle of anthropometric ECG by using mannequin.Methods A mannequin was made using conductive paper with"heart" designed in left chest and its ECG was measured.Results The forming principles of ECG from mannequin and real people were identical.Mannequin had the same physical characteristics as real human body.Conclusion The change of ECG caused by pure physical factors can be studied by using the mannequin,which helps doctors properly analyze ECG and make accurate diagnosis.
