.This data is a subset of hemodynamic data collected as a part of the LASERI study (English title: “Cardivascular risk in young Finns study”) using whole-body impedance cardiography and plethysmographic blood pressure recordings from fingers. The data given here comes from 223 healthy subjects between 26 and 42 years of age, who participated in the recording of the hemodynamic variables both in a supine position and during a passive head-up tilt on a motorized table. During that experiment the subject spent the first ten minutes in a supine position, then the motorized table was tilted to a head-up position (60 degrees) for five minutes, and for the last five minutes the table was again returned to the supine position.
Of interest in this data is for example if the values 5 minutes after the tilt are already returned to their pre-tilt levels.
