dc.description.abstractThis study used the impedance cardiogram (ICG), the phonocardiogram (pCG) and the electrocardiogram (ECG) to determine stroke volume and systolic time intervals. Comparisons between a fully automated PC-AT signal processing system and a computer-assisted visual detection processing system revealed comparable means, standard errors, correlations (Spearman r) and reliability (Chronbach's ex) coefficients on all relevant parameters. Other analyses confIrmed the utility of using Q onset to mark the beginning of ventricular systole, the B point of the ICG to denote the aortic opening and end diastole as the reference for determining the amplitude of dZ/dt max.en
