Summary

Vasovagal syncope in an elderly woman was not managed by temporary pacing alone. Combining a beta-blocker with permanent DDD pacing effectively reduced syncope symptoms.

Area of Science:

  • Cardiology
  • Neurology

Background:

  • Vasovagal syncope can significantly impact quality of life, particularly in elderly patients.
  • Management strategies for refractory vasovagal syncope require further investigation.

Observation:

  • A 74-year-old woman experienced recurrent vasovagal syncope despite being otherwise healthy.
  • Temporary ventricular and atrioventricular sequential pacing failed to prevent syncope episodes.

Findings:

  • Permanent DDD pacing combined with a beta-blocker demonstrated significant clinical success in diminishing vasovagal syncope symptoms.
  • This combination therapy proved more effective than pacing alone.

Implications:

  • The findings suggest a potential therapeutic approach for managing severe or refractory vasovagal syncope.

  • Further research into the synergistic mechanisms of beta-blockers and pacing in syncope is warranted.
