Abstract : Heart Rate Turbulence HRT describing the heart rate changes following a premature ventricular contraction, has been regarded as an indirect index of baroreflex function. However limited data are available on its relation to invasive assessment by phenylephrine injection Phe Slope. We therefore compared these methodologies in a series of heart failure HF patients in which both measures together with clinical and hemodynamic data were available. HRT parameters turbulence onset, TO and turbulence slope, TS, were measured from 24-hour Holter recordings obtained within one week from baroreflex sensitivity assessment and right heart hemodynamic evaluation Swan-Ganz catheter. HRT was computable in 135 out of 157 86% patients who had both phenylephrine test and hemodynamic evaluation. TO and TS significantly correlated with Phe Slope r=-0.39, p
