[Reproducibility of head-up tilt test in patients with neurocardiogenic syncope].
Arq Bras Cardiol. 1994 May; 62(5):297-9.AB

Abstract

PURPOSE

In order to identify the reproducibility of head-up tilt test, a second test one week later in 22 patients with a positive first test, was performed.

METHODS

The test was performed in a fasting state during the morning. The heart rate and blood pressure were monitored during 20 minutes in the supine position and then at 60 degrees for up to 40 minutes. The test were considered positive if the patient experienced syncope or pre-syncope with fall in systolic blood pressure > 30mmHg. The following aspects were evaluated: reproducibility of the positive response; the type of response (hypotension, asystole or hypotension plus bradycardia) and the time interval between tilt and the beginning of symptoms.

RESULTS

Eighteen (82%) patients had a second positive response; 14 (77.8%) of then had the same type of response; and 17 (94%) had syncope in similar time interval after tilt.

CONCLUSION

The head-up tilt testing has good reproducibility, although its use in the therapeutic management needs a longer period of evaluation.
