  • heart rate variability - Variation in the time intervals between heartbeats

    Heart rate variability (HRV) is the physiological phenomenon of variation in the time interval between heartbeats. It is measured by the variation in the beat-to-beat interval. Other terms used include cycle length variability, R–R variability (where R is a point corresponding to the peak of the QRS complex of the ECG wave; and R–R is the interval between successive Rs), and heart period variability. Measurement of the R–R interval (often termed normal-to-normal or N–N interval when additional filtering is used) is used to derive heart rate variability. Methods used to detect beats include ECG, blood pressure, ballistocardiograms, and the pulse wave signal derived from a photoplethysmograph (PPG). ECG is considered the gold standard for HRV measurement because it provides a direct reflection of cardiac electric activity.

  • CNET - American company; tech media website

    CNET (short for Computer Network) is an American media website that publishes reviews, news, articles, blogs, podcasts, and videos on technology and consumer electronics globally. CNET originally produced content for radio and television in addition to its website before applying new media distribution methods through its internet television network, CNET Video, and its podcast and blog networks.
