[Analysis of head-up tilt test responses in patients suffering from syncope and high blood pressure].
We studied the difference in head-up tilt test responses between patients suffering from syncope who had hypertension and those who did not. A total of 338 consecutive patients with syncope underwent head-up tilt testing in our department from January 2003 to October 2004. Of these, 243 did not have hypertension (group A), whereas 95 did (group B). There were significant differences between the...
متن کاملLeg intravenous pressure during head-up tilt.
Leg vascular resistance is calculated as the arterial-venous pressure gradient divided by blood flow. During orthostatic challenges it is assumed that the hydrostatic pressure contributes equally to leg arterial, as well as to leg venous pressure. Because of venous valves, one may question whether, during orthostatic challenges, a continuous hydrostatic column is formed and if leg venous pressu...
متن کاملHead-up-tilt testing in children: new perspectives using beat-to-beat blood-pressure monitoring
The head-up-tilt-test in pediatric patients for the evaluation of syncope shows a sensitivity of 35-85% and often requires pharmacological stimulation in order to improve its diagnostic value. We used a new device for beat-to-beat blood pressure monitoring combined with impedance cardiography in a 12-year-old girl during tilt testing. A seven seconds asystolia was provoked. The haemodynamic par...
متن کاملEndogenous Circadian Rhythm in Vasovagal Response to Head-Up Tilt
Background—The incidence of syncope exhibits a daily pattern with more occurrences in the morning, possibly as a result of influences from the endogenous circadian system and/or the daily pattern of behavioral/emotional stimuli. This study tested the hypothesis that the circadian system modulates cardiovascular responses to postural stress, leading to increased susceptibility to syncope at spec...
متن کاملWhich is preferable for orthostatic hypotension diagnosis in older adults: active standing test or head-up tilt table test?
BACKGROUND Correct evaluation of orthostatic hypotension (OH) is crucial in geriatric practice, since OH is associated with mortality and morbidity. The study aimed to determine the most appropriate method for measuring blood pressure in transition from supine to upright position in order to diagnose OH in older adults. METHODS Active standing test (AST) and head-up tilt table (HUT) test as w...
