Embodiments of this application provide a voice call method and apparatus, and relate to the field of terminal technologies. The method includes: obtaining, by the first terminal device, azimuth information between the first terminal device and the second terminal device based on location information and orientation information of the first terminal device and location information of the second terminal device; and processing, by the first terminal device, a voice signal from the second terminal device based on the azimuth information to obtain a first-channel voice signal and a second-channel voice signal. Then, a first headphone may play the first-channel voice signal and the second-channel voice signal in a first channel and a second channel, respectively. In this way, a user can sense an azimuth status of a peer end during a voice call based on voice fed back by a headphone.

Voice call method and apparatus, electronic device, and computer-readable storage medium

A method and an apparatus for analyzing heart rate Variability (HRV), and use thereof are provided. A low-cost, portable and wearable signal acquisition device is utilized to acquire electrocardiography (ECG) signals of epilepsy patients for 24 hours before treatment, and a time domain index, a frequency domain index and a nonlinear index of the ECG during a long term and during a short term are calculated with a programmed HRV analysis method, and the efficacy of vagus nerve stimulation (VNS) treatment for patients with medically intractable epilepsy is accurately and efficiently predicted based on characteristic parameters for characterizing an effect level of the vagus nerve regulating the heart rate, i.e., vagus nerve activity, thereby avoiding unnecessary costs and avoiding the delay of the optimal treatment timing. In addition, the characteristic parameters obtained by the HRV analysis on the ECG may be utilized to clearly select VNS treatment indication patients.

Heart rate variability analysis method, device and use thereof

A modeling method for screening surgical patients, used in analysis modeling for heart rate variability (HRV). Low-cost, portable and wearable signal acquisition equipment is utilized to acquire an electrocardiography (ECG) signal of an epileptic 24 hours before surgery; a multiscale entropy (MSE) of the ECG is calculated by means of a programmed HRV analysis method, wherein characteristic parameters representing heart rate complexity are extracted on the basis of an MSE curve, and a medical refractory epileptic suitable for vagus nerve stimulation (VNS) surgery is accurately and efficiently screened, thus avoiding unnecessary expenditures and avoiding delaying an optimal opportunity for treatment. Meanwhile, the curative effects of the VNS treatment may be wholly improved by means of clearly selecting VNS surgical indication patients according to the characteristic parameters of the MSE complexity of the ECG.
