This study presents a BSPM system (hardware and platform) to allow users to analyze the characteristics of morphology in up to 64 simultaneous body surface potentials (BSPs) including the 12-lead ECG and vectocardiogram (VCG). The signals undergo a preprocessing step followed by the R peak detection using previously validated techniques for heart rate variability studies. In addition, embedded 3D isopotential, 3D isochrone maps and VCG planes allow researchers to investigate the heart's the electrical activity and its patterns under different heart rhythm disorders in clinical practice.engrestrictedAccessconferenceObjectCopyright IEEE COMPUTER SOC10.22489/CinC.2017.053-337Cardiac & Cardiovascular SystemsComputer Science, Interdisciplinary ApplicationsEngineering, Biomedical
