[Permanent pacemakers: 15 years' experience]
Archivos Del Instituto De Cardiologia De Mexico
|September 1, 1982
Summary
This 15-year study of 200 patients found permanent pacemakers to be a secure and effective treatment for severe arrhythmias, with low pacemaker-attributable mortality despite common complications.
Area of Science:
- Cardiology
- Biomedical Engineering
- Clinical Medicine
Context:
- Analysis of a 15-year experience (1964-1978) with 200 patients requiring definitive pacemakers.
- Patient cohort aged 15-102 years, undergoing 329 generator implantations.
- Focus on long-term pacemaker management and patient outcomes.
Purpose:
- To evaluate the safety and efficacy of permanent pacemaker implantation over a 15-year period.
- To analyze patient demographics, underlying cardiopathies, associated diseases, and rhythm alterations.
- To report on intercurrent complications, generator replacement rates, and pacemaker-attributable mortality.
Summary:
- Predominant cardiopathy was atherosclerotic (172 cases); hypertension was a significant associated disease (30%).
- Atrioventricular block (72%) and trifascicular block (16%) were the most frequent rhythm alterations.
- 17.5% experienced complications (e.g., generator pocket infection); 11% overall mortality, with only 2% pacemaker-related.
Impact:
- Demonstrates the long-term security and effectiveness of permanent pacemakers for severe arrhythmias.
- Provides valuable data on complication rates and management challenges, including generator longevity.
- Supports the continued use of pacemakers as a critical therapeutic option in cardiac care.
