Mobile Application for Visualization and Analysis of Impedance Cardiography Signals.

Area of Science:

• Biomedical Engineering
• Medical Informatics

Background:

• Bioimpedance measurement is a noninvasive technique for assessing internal organ function.
• Impedance cardiography (ICG) is a bioimpedance method used to evaluate cardiac mechanical activity and estimate stroke volume.

Purpose of the Study:

• To develop a mobile application using Java and Android Studio for visualizing ICG and ECG signals.
• To enable preliminary analysis of basic hemodynamic parameters derived from ICG signals.

Main Methods:

• Signal analysis included determining heart rate (HR), stroke volume (SV), cardiac output (CO), and left ventricular ejection time (LVET).
• The application allows users to visually inspect signal quality and manually select key points on ECG and ICG waveforms for calculation.

Main Results:

• The developed program visualizes ICG and ECG signals simultaneously.
• It facilitates the calculation of ICG-derived cardiac parameters through user interaction with waveform data.

Conclusions:

• The application provides a tool for visualizing ECG and ICG signals and calculating hemodynamic parameters.
• It supports preliminary analysis of cardiac function using impedance cardiography data.
