Summary
The number of pacemaker implants in Switzerland rose slightly between 1989 and 1991. During this period, there was a significant shift towards rate-responsive and dual-chamber pacemakers.
Area of Science:
- Cardiology
- Biomedical Engineering
- Public Health
Context:
- Annual pacemaker survey in Switzerland, encompassing nearly all implanted devices.
- Data collected from 50 implanting hospitals over a three-year period (1989-1991).
- Current population of pacemaker patients in Switzerland estimated at 10,000.
Purpose:
- To analyze trends in pacemaker implantation rates and device types in Switzerland.
- To identify changes in clinical indications, ECG-indications, and etiology for pacemaker use.
- To track the adoption of different pacemaker system technologies.
Summary:
- First pacemaker implants increased from 242 to 252 per million population between 1989 and 1991.
- Clinical indications, ECG-indications, and etiology remained largely unchanged.
- Significant increase in rate-responsive single-chamber pacemakers (25% to 34%) and dual-chamber pacemakers (14% to 21%).
Impact:
- Highlights a technological shift in pacemaker selection towards more advanced systems.
- Provides valuable data for healthcare planning and resource allocation in cardiac pacing.
- Informs future research on the long-term benefits and outcomes of rate-responsive and dual-chamber pacing.
