Coherent ensemble averaging techniques for impedance cardiography
EKG synchronized ensemble averaging of the impedance cardiogram tends to blur or suppress signal events due to signal jitter or event latency variability. Although ensemble averaging provides some improvement in the stability of the signal and signal to noise ratio under conditions of nonperiodic influences of respiration and motion, coherent averaging techniques were developed to determine whe...
متن کاملImpedance pneumography: noise as signal in impedance cardiography.
Thoracic impedance is modulated by events within the respiratory cycle, which represents a source of "noise" in impedance cardiography. Respiration itself, however, is a physiological rhythm of interest to psychophysiologists. We report here methods and validation for deriving impedance pneumographic measures of respiration from impedance cardiography signals, based on standard tetrapolar band ...
متن کاملNoninvasive hemodynamic monitoring in heart failure: utilization of impedance cardiography.
The annual health care cost incurred by heart failure patients is about $56 billion, two thirds of which is spent on management of acutely decompensated patients. Hemodynamic evaluation is helpful for optimization of treatment, monitoring clinical outcomes, and overall prognostication of heart failure patients, but historically could only be obtained via costly invasive procedures that carry su...
متن کاملImproved Detection of Ventricular Ejection Time for Impedance Cardiography
Impedance cardiography is a noninvasive technique for monitoring stroke volume (SV), based on sensing variation in the thoracic impedance due to blood flow. In this technique, first derivative of impedance (dz/dt) is used to calculate two parameters: ventricular ejection time and (-dz/dt)max. Respiration and motion artifacts cause base line drift in the sensed impedance waveform, and this resul...
متن کاملImpedance Cardiography *
Objective: To evaluate the following: (1) the intramethod variability of impedance cardiography (ICG) cardiac output (CO) measurements via the latest generation monitor and thermodilution CO measurements (CO-TDs); (2) the intermethod comparison of ICG CO and CO-TD; and (3) comparisons of the intergeneration ICG CO equation to CO-TD, using the latest ICG CO equation, the ZMARC (CO-ICG), and the ...
