Ejection Fraction Measurement Based on Impedance Cardiography
Ejection fraction (EF) is an important indicator of cardiac function, especially in clinical conditions. Unlike imaging technology such as echocardiography, impedance cardiography (ICG) is a low-cost, non-invasive and continuous method of monitoring EF. However, the accuracy of the ICG method to eva...

| description | Ejection fraction (EF) is an important indicator of cardiac function, especially in clinical conditions. Unlike imaging technology such as echocardiography, impedance cardiography (ICG) is a low-cost, non-invasive and continuous method of monitoring EF. However, the accuracy of the ICG method to evaluate the EF value needs to be further improved. This paper uses a simplified ventricular model to simplify the complex relationship between the EF value and the relevant ICG parameters, and proposes a method for calculating the EF value through these relevant ICG parameters. We tested this method with 52 subjects. Experimental results show that compared with the traditional ICG method, the proposed method has a higher correlation and closer agreement with the EF measurement by echocardiography. The proposed scheme effectively improves the reliability of the measurement of the EF value relying on the ICG signal. |
