心阻抗图（impedance cardiogram，ICG）又称心阻抗血流图。 是用电生物阻抗技术测定心输出量，评判心脏功能的无创性方法。 与心电图，心音图、颈动脉搏动图同步记录，还可测定心脏收缩和舒张时间间期，血管顺应性及总外周阻力等。

Impedance cardiography (ICG) is a non-invasive technology measuring total electrical conductivity of the thorax and its changes in time to process continuously a number of cardiodynamic parameters, such as stroke volume (SV), heart rate (HR), cardiac output (CO), ventricular ejection time (VET), pre-ejection period and used to detect the ...

In this paper, we present a measurement system for the acquisition of ICG and one-lead ECG signal simultaneously using the same electrodes for both measurements. The Pan-Thompkins algorithm is used for ECG analysis, and the ensemble average method is applied to assess hemodynamic parameters of the ICG signal. 2. Methods. 2.1. Z-RPI Device.

Monitoring Electrocardiogram (ECG) and Impedance Cardiography (ICG) simultaneously can help evaluate cardiovascular disease comprehensively. However most of the ICG monitoring devices are...

Electrical bioimpedance studies the impedance in the human body. It allows obtaining continuous and real-time hemodynamic data measurements as well as the diagnosis of several cardiovascular diseases, in particular by using the impedance cardiography (ICG) technique.

AcqKnowledge ® offers a comprehensive array of noninvasive impedance cardiography (ICG) tools for recording parameters associated with virtually any kind of electrical bioimpedance (EBI) monitoring and bioimpedance analysis (BIA). Extracted measures can be displayed as new channels in the recording, or exported to an Excel spreadsheet or ...

The impedance cardiography (ICG) dZ/dt signal captures the velocity changes of the blood allows estimating pre-ejection period (PEP), left-ventricular ejection time (LVET), and stroke volume, among other cardiovascular parameters.

Nov 29, 2018 · This paper presents the feasibility of recording an ICG signal simultaneously with electrocardiogram signal (ECG) using the same electrodes for both measurements, for a total of five electrodes...

心电图（Electrocardiogram，简称ECG或EKG）是一种记录心脏电活动的医学测试。 它通过在身体表面放置一系列电极捕捉并记录心脏每次跳动时产生的微小电脉冲。

Feb 26, 2024 · 读懂心电图（ECG）需要对其基本组成部分有一定的了解，并能够识别各种波形和间隔所代表的心脏活动。 以下是读懂心电图的基本步骤： 1. **了解基本概念**： - ** P波 **：代表心房除极（心房收缩），代表了心房的激动，一般呈钝圆形。 - ** QRS复合波 **：代表心室除极（心室收缩）。 正常情况下，Q波是第一个负波，R波是随后的正波，S波是最后的负波。 - ** T波 **：QRS复合波之后的一个较大的向上的波，代表心室复极（心室舒张），T波应与QRS主波 …
