title = "Influence of signal fidelity on impedance cardiographically-derived values at resting and accelerated heart rates",
abstract = "This study was designed to assess the influence of amplifier bandwidth and signal fidelity on dZ/dtmax, stroke volume (SV), and systolic time intervals (LVET, PEP, QZ HI). The performance of commonly available commercial systems was tested over a broad range of heart rates. The results demonstrated that a digitally differentiated dZ/dt signal using a differentiator with a corner frequency of 50 Hz, when compared with the 15 Hz corner frequency used in the commercial impedance cardiograph, systematically enhanced the dZ/dtmax amplitude and SV measurements as the heart rate increased.",
