متن کاملRole of endogenous adenosine as a modulator of syncope induced during tilt testing.
BACKGROUND Previous reports that used head-up tilt testing and adenosine administration have suggested that adenosine may be an important endogenous mediator that may trigger a vasovagal response in susceptible patients. However, little is known regarding endogenous adenosine plasma levels (APLs) during vasovagal syncope provoked by tilt testing. The aim of this study was to determine whether A...
متن کاملThe normal response to prolonged passive head up tilt testing.
OBJECTIVE To define the responses to head up tilt in a large group of normal adult subjects using the most widely employed protocol for tilt testing. METHODS 127 normal subjects aged 19-88 years (mean (SD), 49 (20) years) without a previous history of syncope underwent tilt testing at 60 degrees for 45 minutes or until syncope intervened.
