Abstract
Described here are methods, devices, and systems for characterizing a physiological signal, and more specifically an electrocardiogram (ECG) signal. Generally, the method includes receiving an ECG signal generated by an ECG device coupled to a patient. The ECG signal may comprise a plurality of cardiac beat intervals. A set of evaluable replicates may be identified using a signal-to-noise ratio (SNR) for each cardiac beat, a repolarization signal, and an isoelectric line. Interval measurements may be determined from the set of evaluable multi-beat sequences. An ECG signal characteristic may be determined from the interval measurements.
