Abstract :
The purpose of this work was an improvement of the heart micropotential measurements and analysis by the simultaneous use of two non-invasive methods: body surface mapping and high-resolution electrocardiography. Software for body surface mapping and multi-lead high-resolution ECG analysis was developed. An analysis of the QRS duration and the energy of a 25-ms interval in a terminal QRS complex was applied both for each single lead and for an orthogonal X,Y,Z lead system. Results were visualized on a 3D torso. Preliminary recording was carried out on three normal subjects and on three myocardial infarction patients
