Feasibility, reproducibility and accuracy of electrical velocimetry for cardiac output assessment in congenital heart disease
2020, IJC Heart and VasculatureCitation Excerpt :Electrical velocimetry (EV) is an impedance cardiography technique that provides continuous assessment of stroke volume and cardiac output by measuring the maximum rate of change of impedance to peak aortic blood acceleration [12]. Some studies have reported good correction between cardiac output assessment by EV and invasive hemodynamic assessment [12–16]. However, the feasibility and reproducibility of EV cardiac output assessment under different loading conditions have not been studied.
Electrical Cardiometry: A Reliable Solution to Cardiac Output Estimation in Children With Structural Heart Disease
2017, Journal of Cardiothoracic and Vascular AnesthesiaCitation Excerpt :According to the theory of EC, erythrocytes change their random orientation in the descending aorta during diastole to linear alignment as the heart begins to eject in systole. Bioimpedance-based previous studies have shown mixed results when comparing impedance cardiography with PAC-derived CO.10,20–22 Using the earliest versions of electrical impedance cardiography, Braden et al20 and Miles et al21 found good correlation between impedance cardiography and PAC-derived CO in young children with a variety of congenital heart diseases. Heringlake et al22 and Tomasaki et al,23 on the other hand, demonstrated a disagreement between these two methods before and after elective cardiac surgery, indicating a percentage error of 34% to 67%.
Electrical velocimetry for measuring cardiac output in children with congenital heart disease
2008, British Journal of AnaesthesiaCitation Excerpt :A P-value of <0.05 was considered statistically significant. Secondly, to assess agreement between COEV and COF, the method of Bland and Altman16 was employed, by computing bias, precision, and limits of agreement. The details of the patients, VO2 index (ml kg−1 m−2), haemoglobin (g dl−1), Sao2 (%), and CHD diagnosis are given in Table 1.
Usefulness of an Abnormal Cardiovascular Response During Low-Grade Head-Up Tilt-Test for Discriminating Adolescents With Chronic Fatigue from Healthy Controls
2007, American Journal of CardiologyCitation Excerpt :Beat-to-beat stroke volume and end-diastolic volume of the left ventricle were calculated from the impedance signal.13,17 This method has been validated in adults18 and children.19 The highest positive slope of the impedance signal (d2Z/dt2max) corresponds to the maximal acceleration of blood flow during the ejection phase and is thus partly dependent on the inotropic state of the myocardium.20
