The purpose of this study was to observe the hemodynamic changes of unexplained syncope patients in the head-up tilt test and their correlations with age and gender. Eighty-six patients with unexplained syncope were administered the basic head-up test and nitroglycerin provocation test with continuous monitoring and recording of electrocardiogram and blood pressure changes. Basic characteristics of the patients and their hemodynamic responses throughout the tests were analyzed. All 86 patients tolerated and completed the head-up test.
