Variable cerebral dysfunction during tilt induced vasovagal syncope.
Electroencephalographic (EEG) monitoring was performed during head-up tilt testing (HUT) in a group of 63 consecutive patients (27 males, 36 females, mean age 41.5 years) with a history of recurrent syncope of unknown origin despite extensive clinical and laboratory evaluation. Syncope occurred in 27/63 patients (42.8%) during HUT and was cardioinhibitory in 11/27 (40.7%) and vasodepressor in 1...
متن کاملClinical features of adenosine sensitive syncope and tilt induced vasovagal syncope.
AIM To evaluate the possible relation between adenosine sensitive syncope and tilt induced vasovagal syncope. METHODS An ATP test and a head up tilt test were performed in 175 consecutive patients with syncope of uncertain origin. The ATP test consisted of the rapid intravenous injection of 20 mg of ATP; a positive response was defined as the induction of a ventricular pause (maximum RR inter...
متن کاملThe effect of atropine in vasovagal syncope induced by head-up tilt testing.
AIMS This single-blinded, randomized, placebo-controlled study was designed and undertaken to assess the efficacy of intravenous atropine administration on haemodynamic impairment induced by head-up tilt testing in patients with vasovagal syncope. METHODS AND RESULTS One hundred and thirteen consecutive patients (62 male and 51 female, mean age 46.3 years) with recurrent syncope, no evidence ...
متن کاملElectroencephalographic correlates of vasovagal syncope induced by head-up tilt testing.
BACKGROUND AND PURPOSE We sought to determine whether the introduction of EEG monitoring during head-up tilt testing could significantly improve the understanding of the cerebral events occurring during tilt-induced vasovagal syncope and the potential danger to the patient of this diagnostic procedure. METHODS EEG monitoring was performed during head-up tilt testing in a group of 63 consecuti...
متن کاملEfficacy of tilt training in patients with vasovagal syncope.
BACKGROUND Besides pharmacological therapy and pacemaker implantation, tilt training is a promising method of treatment in patients with vasovagal syncope (VVS). Tilt training is usually offered to patients with malignant or recurrent VVS which impairs their quality of life and carries a risk of injury. AIM To assess the efficacy of tilt training in patients with VVS. METHODS The study grou...
