Electrocardiographic (ECG) scanner is a system for electrocardiological diagnostics by combining original ECG leads having known spatial positions into synthesized ECG leads having arbitrary spatial positions, analyzing electric signals of synthesized ECG leads, and producing scalar tracings (synthesized ECGs) in them. An ECG scanner automatically scans the three-dimensional space formed of a boundless number of synthesized ECG leads to detect the one which is collinear with a pathology and where earlier invisible or poorly discernible pathological ECG signs become noticeable or more manifesting and reaching diagnostic thresholds. An ECG scanner reveals diagnostically valuable information that is ordinarily lost in conventional electrocardiography and vectorcardiography. An automated ECG scanner includes: a device for systematically combining original ECG leads; a device for controlling parameters of combining ECG leads; a device for adjusting for a particular patient parameters of combining ECG leads; a device for analyzing electric signals of synthesized ECG leads; and a device for visualizing electric signals and positions of synthesized ECG leads. Supplementary devices are disclosed. A cardiac imaging system for matching heart structures of a patient with ECG signals originating therefrom is disclosed. A three-dimensional manipulator for manually ECG scanning is depicted.
