Abstract
An electrocardiogram (ECG) system provides a set of ECG lead signals. The system includes a source of a subset of ECG lead signals. A synthesizer, coupled to the ECG lead signal source, generates a set of synthesized ECG lead signals from the subset of ECG lead signals. Data is also generated representing the accuracy of the set of synthesized ECG lead signals.
