Sentence examples for multiple impedance vectors from inspiring English sources

Panescu et al. examined multiple impedance vectors derived from implanted biventricular implantable cardioverter-defibrillator devices in a canine/ovine model of heart failure, and demonstrated good correlation between cardiogenic impedance and progression of heart failure.

We compared the fluid volume parameters in women undergoing gynaecological surgery for benign and malignant conditions before and after surgery using bioelectrical impedance vectors.

Figure 5 shows the relationship between admittance and LAP for the LVring-case and RVcoil-case impedance vectors.

All impedance vectors decreased in proportion to HF severity (all P<0.001), with the LVring (left ventricular -case ventricular -caseg best with LAP (r=0.63, P<0.001).

All six impedance vectors decreased in response to rapid ventricular pacing, with vectors utilizing the LV lead exhibiting the best correlation with LAP (r=0.63) and vectors utilizing the RV lead demonstrating a somewhat reduced correlation with LAP (r=0.50).

The mean impedance vectors of groups with differing sarcopenia status were compared with the Hotelling's T test and graphically compared with the 95% probability confidence ellipses.

Impedance vectors were accepted for further analysis if there was an absence of a lead disturbance artifact, which was detected when there was a significant instability in the impedance measurements (>80 Ω) between those obtained at the onset of the protocol (baseline period) and those obtained following the recovery period (beyond day 32).
