[The Study of the Measurement of Heart Rate Variability Using ECG and Photoplethysmographic Signal].
In comparison with the measurement of heart rate variability from ECG and from photoplethysmographic signal from 46 healthy adults in their spontaneous breathing state. The beat-to-beat intervals in ECG and pulse-to-pulse intervals in photoplethysmographic signal are extracted, and then the parameters of heart rate variability are calculated. ⋯ The results show that the correlation coefficients of the HRV parameters in the two calculation methods are highly correlated. The Bland-Altman scattered plots show the relative bias results from the algorithm of the maximum of PPG signal are smallest and singular points that deviate from the consistent limits are the least compared with the other two algorithms.

The regulation of mobile medical devices is one of the hot topics in the industry now. The definition, regulation scope and requirements, potential risks of mobile medical devices were analyzed and discussed based on mobile computing techniques and the FDA guidance of mobile medical applications. The regulation work of mobile medical devices in China needs to adopt the risk-based method.
