QTVIEComparaison Des Intervalles QT/QTc Entre Une Population HIV Positive Ambulatoire Sous thérapie antirétrovirale et Une Population Ambulatoire HIV négative

Primary objective: The primary objective is to compare the QT/QTc intervals of HIV positive subjects treated with antiretroviral therapy and followed at the ambulatory HIV clinic and the QT/QTc intervals of : an outpatient HIV negative population from the same health center pre-admission one-day surgical clinic. the large HIV-free korean population studied in the ECG-ViEW database. Secondary objectives : Evaluate the prevalence of QTc interval prolongation in the outpatient HIV positive population comparatively to the two HIV negative outpatient populations available from the one-day surgical clinic and the ECG-ViEW database. Evaluate risk factors associated with QTc interval prolongation in the outpatient HIV positive population compared to the outpatient HIV negative population and the population studied in the ECG-ViEW database. Compare the QT/QTc intervals and the prevalence of QTc interval prolongation of the outpatient HIV positive population currently on an antiretroviral regimen including a protease inhibitor versus those on an antiretroviral regimen without protease inhibitor. Compare the QT/QTc intervals among the outpatient HIV positive population treated with a protease inhibitor, in regard to the presence or the absence of certain genetic polymorphisms that may influence pharmacokinetic aspects of protease inhibitors.
