Title: Innovations by Hongyun Liu in Heart Rate Variability Analysis

Introduction

Hongyun Liu is a notable inventor based in Beijing, China. He has made significant contributions to the field of medical technology, particularly in the analysis of heart rate variability (HRV). With a total of 4 patents, his work focuses on improving treatment methods for epilepsy patients.

Latest Patents

One of his latest patents is a heart rate variability analysis method, device, and use thereof. This invention provides a method and apparatus for analyzing HRV, utilizing a low-cost, portable, and wearable signal acquisition device to collect electrocardiography (ECG) signals from epilepsy patients for 24 hours prior to treatment. The analysis includes calculating time domain, frequency domain, and nonlinear indices of the ECG, which helps predict the efficacy of vagus nerve stimulation (VNS) treatment. This innovation aims to avoid unnecessary costs and delays in optimal treatment timing.

Another significant patent is a modeling method for screening surgical patients. This method employs a similar low-cost, portable device to acquire ECG signals from epileptic patients 24 hours before surgery. By calculating multiscale entropy (MSE) of the ECG, characteristic parameters representing heart rate complexity are extracted. This allows for the accurate screening of patients suitable for VNS surgery, thereby improving treatment outcomes and reducing unnecessary expenditures.
