Nouvelles approches en cardiographie d'impédance

The relevance of measuring cardiac output in cardiology is obvious. However the commonly used systems for cardiac output measurement, invasive or not, are outdated. A new generation of impedance cardiograph (ICG), PhysioFlow™, has been developped around a major improvement: the morphological analysis of the impedance signal. This method avoids the limitations of standard ICG using the impedance baseline. These limitations included: operator skill dependency, no obesity, no emphysema and only for immobile patients or very moderate exercise. Using a new high tech filtering technology and pure signal morphology analysis, those new technologies features an accuracy that is now comparable to invasive techniques even in demanding measurement conditions. Furthermore, its clinical reproducibility and sensitivity are unsurpassed. The analysis of the impedance wave-form and the use of software tools like the hemodynamic cross help practitioners to identify anomalies, to diagnose more pathology earlier, to optimize treatments and to evaluate their efficacy.
