Area of Science:

  • Cardiology
  • Neurology

Background:

  • Sinus node dysfunction can cause syncope, leading to diagnostic challenges.
  • Implantable loop recorders (ILRs) aid in diagnosing infrequent cardiac events.

Observation:

  • A truck driver with recurrent unexplained syncope underwent prolonged monitoring.
  • An implantable loop recorder was implanted for diagnostic purposes.

Findings:

  • Sinus node dysfunction was diagnosed over 18 months after implantable loop recorder implantation.
  • The diagnosis of cardiogenic syncope was elusive despite extensive prior testing.

Implications:

  • This case highlights the diagnostic difficulties in infrequent cardiogenic syncope.
  • Prolonged monitoring with implantable loop recorders is crucial for diagnosing rare cardiac arrhythmias.
