[Swiss pacemaker statistics of the year 1982]

Area of Science:

• Cardiology
• Medical Device Technology
• Public Health Surveillance

Background:

• Pacemaker implantation is a common procedure for managing cardiac rhythm disorders.
• Monitoring trends in pacemaker use and outcomes is crucial for healthcare planning.
• Switzerland has a robust system for collecting healthcare data.

Purpose of the Study:

• To analyze the trends in pacemaker implantations in Switzerland using comprehensive national data.
• To compare current implantation rates, device types, and indications with previous years.
• To assess the impact of increased implantations on complication rates.

Main Methods:

• Analysis of national data covering 96% of pacemaker implantations in Switzerland.
• Comparison of implantation data from the current period with historical trends.
• Evaluation of device types (multiprogrammable, physiologic) and indications.
• Assessment of complication rates requiring reintervention.

Main Results:

• First pacemaker implantations increased slightly to 216 per million population annually.
• The proportion of multiprogrammable pacemakers reached two-thirds of all devices implanted.
• Implantation of physiologic pacemakers rose to 8.8% of cases.
• Despite an increase in first implantations, complication rates requiring reintervention decreased.

Conclusions:

• Pacemaker implantation trends in Switzerland show a modest increase in first-time procedures.
• There is a growing adoption of advanced pacemaker technologies, including multiprogrammable and physiologic devices.
• Improved implantation practices or device technology may be contributing to a reduction in complication rates.
