摘要： Cardiac signal data of heart beats measured with an ambulatory electrocardiography device is accessed. The cardiac signal data is segmented into cardiac signal data segments such that each cardiac signal data segment includes cardiac signal data of sequential heart beats. Whether alternans is present in the cardiac signal data segment is determined for each of multiple cardiac signal data segments. Characteristics of the alternans is determined by analyzing cardiac signal data segments for which alternans is determined to be present or by analyzing characteristics of cardiac signal data segments for which alternans is determined to be present.

摘要： A signal-based cable attenuation measurement device, system and methodology provides measurement of attenuation characteristics of a cable over a wide frequency spectrum. Located at a single location on a cable, a measurement device injects a signal on to the cable under measurement and receives the reflected signal, recording physical characteristics of the cable in response to the signal. A model, calibrated to estimate the effects of the cable with known impedances, evaluates the waveform generated from the cable's response to the signal and computes attenuation of the cable as a function of frequency. In some circumstances, when low signal-to-noise effects result, normally at high frequencies in long cables, the attenuation of the cable is further fitted to the model to correct the errors that occur as a result of the low signal-to-noise effects.

摘要： Alternans is measured in a physiological signal, such as an electrocardiogram, by processing the physiological signal to create a processed signal having an asymmetric spectrum, and processing the processed signal to measure alternans in the physiologic signal. The physiological signal may be processed to produce an analytical signal by converting the signal to the frequency domain, removing components corresponding to negative frequencies, and converting back to the time domain.
