Title: Innovations in Cardiac Monitoring by Xu-Sheng Zhang

Introduction

Xu-Sheng Zhang is a notable inventor based in Santa Ana Heights, CA (US). He has made significant contributions to the field of cardiac monitoring, particularly in the detection of tachyarrhythmias. With a total of 2 patents, his work focuses on improving the accuracy and reliability of cardiac arrhythmia detection systems.

Latest Patents

Xu-Sheng Zhang's latest patents include a system and method for complexity analysis-based cardiac tachyarrhythmia detection. This innovative system utilizes electrocardiogram (ECG) complexity analysis to detect shockable ventricular fibrillation (VF) and ventricular tachycardia (VT) in real-time. It effectively discriminates these conditions from non-shockable tachyarrhythmias, such as supraventricular tachycardia (SVT) and atrial fibrillation (AF), as well as high-frequency noise. The complexity measure (CM), which ranges from 0 to 100, characterizes the non-linear dynamics underlying cardiac arrhythmia. By applying three thresholds, the system can differentiate between various types of tachyarrhythmias and high-frequency noise.

Another significant patent by Zhang is a cardiac arrhythmia detector that uses ECG waveform-factor and its irregularity. This device monitors the heart condition of patients and generates signals indicating several conditions, including supraventricular tachycardia, ventricular tachycardia, and ventricular fibrillation. The ECG is analyzed to determine cardiac intervals and heart rates, as well as to derive a waveform factor and its irregularity. This information is crucial for detecting shockable ventricular arrhythmias.
