Abstract :
Blood pressure dynamicity during tilt table measurement is discussed. We analyzed ECG and BP parameters from 14 normotensive young healthy volunteers, 15 old healthy volunteers, and two groups of hypertensive patients - 20 non-medicated hypertensive subjects with no other known complications and 21 hypertensive non-medicated subjects with confirmed obesity (according to waist circumference), hyperlipidemia or diabetes mellitus. The dynamic parameters, such as pulse pressure, maximum of derivative BP, difference between maximum and minimum of derivative BP and SBP peak - DBP depression time were obtained from derivative continuous blood pressure signal recordings. We have found that the age factor plays a more significant role in dynamic parameters change and in inter-group differentiation than additional risk factors of hypertensive subjects.
