[Upright tilt table testing and syncope evaluation].
Syncope is a state of unconsciousness, the process of syncope is sudden and transient. Transient and widespread cerebral ischemia/hypoxia are the reasons of syncope. Sixty percent to seventy percent of the patients suffering from syncope have no categorical reasoning, although lots of assisted examinations had been carried out. Those syncope are called unexplained syncope or unknown origin syncope. Basic upright tilt table test, as well as isoproterenol tilt table test, is a quite effective diagnostic technique for unexplained syncope. This paper reviewed the value of upright tilt [correction of tile] table test in diagnosing unexplained syncope. The method of experiment, information of it's clinical application and points for attention with test were also introduced.
