THE TILT TABLE TEST OF SYNCOPE AND RECESSIVE SYNCOPE IN OLD AGE
Background: A part of Middle-aged and elderly people often appear a transient disturbance of consciousness and recessive syncope of unknown reason and with no symptoms in life. The tilt table test can diagnose it clearly and qualitatively.
Aims: To discuss the relationship among the elderly syncope and recessive syncope and takeing nitroglycerin about tilt table test.
Methods: First, we chose 35 cases unknown causes of syncope and 15 cases no syncope in elderly patients with tilt table test, definited the positive patients;then,the negative patients took nitroglycerin (dose for 5 mg)with tilt table test.
- The tilt table test positive rate of syncope group is 40% (12/30), control group is 0 (P < 0.05).
- Positive rate of syncope group of taking nitroglycerin with tilt table test is 72.2% (13/18), and the control group is 20% (3/15) (P < 0.05).
- Positive rate of taking nitroglycerin with tilt table test is 48.5% (16/33).
Conclusions: Taking nitroglycerin with tilt table test has the very good sensitivity and specificity to diagnosis of syncope and recessive syncope in old people, and the operation is simple, safe and reliable. It is worth clinical application.
