Abstract: A system (10) is disclosed that includes a monitor (16) for use in performing 12-lead electrocardiographic (ECG) and body surface mapping (BSM) analyses on a patient (12) with a single ten-electrode cable set (14). The monitor receives nine leads of data from the electrode cable set and initially preprocesses it to simplify further analysis. Then the data is transformed to produce a spatial distribution relative to the patient's chest, representative of the data that would be collectible with a 192-electrode set. Feature extraction techniques are also described for use in evaluating transformed, as well as conventional, BSM data with respect to clinically evaluated populations. In that regard, features of interest are extracted from the data and statistically analyzed to detect select cardiac conditions.
