Summary

Monocentric cohort study, prospective, evaluating the variability of cardiac output measurement by resting and stress impedancemetry as a prognostic factor for Pulmonary Hypertension

Detailed description

Cardiac impedancemetry is a technique that allows an electrical representation of cardiac flows. To do this, 6 electrodes are applied to the thorax and a low intensity and high frequency electrical current is transmitted. The impedance is recorded and the variations of the impedance represent the changes in intra-thoracic volume and thus the volume of systolic ejection. This measurement can be done at rest but also during exercise during the walking test. A test of the NO / CO coupled transfer measurement is also performed. The devices that will be used in this project are the Physio-Flow® system and Masterscreen NO / CO coupled transfer measurement device
