title: Immediate reproducibility of tilt-table test results in elderly patients referred for evaluation of syncope or presyncope.
abstract: We studied the immediate reproducibility of the results of the head-up tilt-table test in elderly patients (age > or =60 years). Twenty-seven consecutive men underwent 51 tests. The overall reproducibility was 98%, including 92% of a positive test and 100% of a negative test. The finding of this study validates the use of intravenous pharmacologic intervention in the elderly population.
