Impedance cardiography – optimization and efficacy evaluation of antihypertensive treatment

Impedance Cardiography to Guide Antihypertensive Treatment in a Patient with Difficult-to-Treat Hypertension

In this case report, we describe the use of impedance cardiography (ICG) to guide antihypertensive therapy in a patient with difficult-to-treat hypertension illustrating the potential benefit of use in clinical practice. Through the identification of our patient’s hemodynamic phenotype, low cardiac index and elevated systemic vascular resistance index, and medication changes directed toward the...

Impedance 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 ...

Impedance Cardiography Accurately

Objectives: After validation of impedance cardiography (ICG) in healthy children, this same device was tested in children with cystic fibrosis (CF) to validate its capability of measuring cardiac output (Q) in this population. Design: Comparative study of ICG vs the indirect Fick (C02) method. Setting: Tertiary care children's teaching hospital. Patients: Twenty-one CF children with mean FEVX o...

Impedance cardiography revisited.

UNLABELLED Previously reported comparisons between cardiac output (CO) results in patients with cardiac conditions measured by thoracic impedance cardiography (TIC) versus thermodilution (TD) reveal upper and lower limits of agreement with two standard deviations (2SD) of approximately +/-2.2 l min(-1), a 44% disparity between the two technologies. We show here that if the electrodes are placed...
