Neurally mediated syncope, often vasovagal, is the most common cause of fainting in patients without heart disease. Head-up tilt-table testing is valuable for diagnosis and treatment planning.

Area of Science:

  • Cardiology
  • Neurology
  • Clinical Medicine

Background:

  • Syncope is a frequent clinical issue with diverse etiologies.
  • Understanding recurrent syncope requires evaluating natural history and common causes.
  • Medical history and physical exams are crucial for syncope assessment.

Purpose of the Study:

  • To review the diagnostic utility of head-up tilt-table testing for neurally mediated syncope.
  • To discuss the role of electrophysiologic testing in syncope evaluation.
  • To provide insights into optimal tilt-table testing protocols.

Main Methods:

  • Review of recent studies on syncope natural history and causes.
  • Analysis of the role of clinical electrophysiologic testing.
  • Evaluation of head-up tilt-table testing protocols and outcomes.

Main Results:

  • Neurally mediated syncope, especially vasovagal, is the primary cause in patients without structural heart disease.
  • Head-up tilt-table testing is effective for diagnosing neurally mediated syncope.
  • Tilt-test durations of 25 minutes (with pharmacologic provocation) or 45 minutes (without) are suggested.

Conclusions:

  • Head-up tilt-table testing is sensitive and specific for identifying neurally mediated syncopal syndromes.
  • Diagnostic strategies for syncope should differentiate between structural heart disease and neurally mediated causes.
  • Optimized tilt-table testing protocols aid in managing patients with recurrent syncope.
