Noninvasive 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 کاملImpedance cardiography for monitoring changes in cardiac output.
Impedance Cardiography (ICG) is a non invasive method useful for continuous monitoring of cardiac output but, it still has not found wide usage for measuring cardiac output in clinics and research. Most studies focused on comparing the cardiac output measured at rest with reference methods. In the present study we evaluated the validity of ICG against Doppler Echocardiography (DE) in measuring ...
متن کاملValidation of thoracic impedance cardiography by echocardiography in healthy late pregnancy
BACKGROUND Assessment of stroke volume (SV) is often necessary in clinical and research settings. The clinically established method for SV assessment in pregnancy is echocardiography, but given its limitations, it is not always an appropriate measurement tool. Thoracic impedance cardiography (ICG) allows continuous, non-invasive SV assessment. However, SV determination relies on assumptions reg...
متن کاملImpedance Cardiography for Cardiac Output Estimation
everal studies suggest the importance of cardiac power output calculation, which is derived from cardiac output (CO) and mean blood pressure, to predict the prognosis in heart failure patients not only in hospital but also in the outpatient setting.1–3 CO measured by the thermodilution method with a Swan-Ganz catheter placed in the pulmonary artery has become one of the most widely accepted and...
متن کاملBench to bedside: electrophysiologic and clinical principles of noninvasive hemodynamic monitoring using impedance cardiography.
The evaluation of the hemodynamic state of the severely ill patient is a common problem in emergency medicine. While conventional vital signs offer some insight into delineating the circulatory pathophysiology, it is often impossible to determine the true clinical state from an analysis of blood pressure and heart rate alone. Cardiac output measurements by thermodilution have been the criterion...
