Permanent cardiac pacing for neurocardiogenic syncope

Area of Science:

• Cardiology
• Geriatrics
• Neurosurgery

Background:

• Vasovagal syncope poses significant risks in the elderly, impacting quality of life.
• Conservative therapies are often ineffective for severe cases.
• Cardiac pacing is a debated treatment for vasovagal syncope recurrence.

Purpose of the Study:

• To evaluate the long-term effectiveness of pacemaker therapy for vasovagal syncope in elderly patients.
• To determine the efficacy of cardiac pacing in cases refractory to conservative treatment.

Main Methods:

• Utilized the Head-Up Tilt Test (HUTT) since 1996 for vasovagal syncope diagnosis.
• Identified patients with a dominant cardioinhibitory response during HUTT.
• Assessed pacemaker therapy effectiveness in elderly patients with refractory vasovagal syncope.

Main Results:

• A dominant cardioinhibitory response was observed in 4.5% of patients.
• Pacemaker therapy proved highly effective in preventing syncope recurrence.
• Long-term follow-up demonstrated sustained benefits of cardiac pacing.

Conclusions:

• Pacemaker therapy is a viable and effective treatment for elderly patients with severe, refractory vasovagal syncope.
• The study supports cardiac pacing for vasovagal syncope with a dominant cardioinhibitory component.
• Effective management of vasovagal syncope in the elderly can be achieved with appropriate interventions.
