The head-up tilt test (HUTT) diagnosed neurally mediated syncope in many patients. In rare cases, HUTT identified pseudosyncope, suggesting a psychiatric link in unexplained fainting.

Area of Science:

  • Cardiology
  • Neurology
  • Psychiatry

Background:

  • Unexplained syncope presents a diagnostic challenge.
  • The head-up tilt test (HUTT) is a key diagnostic tool for syncope.

Observation:

  • HUTT identified neurally mediated syncope in 266 of 986 patients.
  • A small subset of patients experienced prolonged loss of consciousness during HUTT without hemodynamic changes.

Findings:

  • This phenomenon, termed 'pseudosyncope,' was observed in 3 patients (0.3% of total).
  • Pseudosyncope during HUTT was linked to psychiatric disorders.
  • The test outcome for pseudosyncope was considered a true positive, mirroring clinical events.

Implications:

  • HUTT can aid in identifying psychiatric conditions in patients with unexplained syncope.
