Complications after single versus dual chamber pacemaker implantation.
Pacing and Clinical Electrophysiology : PACE
|June 1, 1990
Summary
Dual chamber (DDD) and single chamber (VVI) pacing systems show similar complication rates. This prospective analysis found no increased risk with dual chamber pacing, supporting its use in patients needing pacemakers.
Area of Science:
- Cardiology
- Medical Devices
- Clinical Research
Background:
- Pacemaker systems are crucial for managing cardiac rhythm disorders.
- Dual chamber (DDD) and single chamber (VVI) pacing offer different functionalities.
- Understanding complication rates is essential for optimal patient care.
Purpose of the Study:
- To prospectively compare the complication rates between dual chamber (DDD) and single chamber (VVI) pacemaker systems.
- To evaluate the safety and efficacy of different pacemaker types.
Main Methods:
- Prospective analysis of 337 consecutive pacemaker procedures over a 3-year period.
- Categorization of patients into VVI (n=258) and DDD (n=75) groups.
- Systematic recording and comparison of reinterventions, lead displacement, infection, muscular stimulation, and reprogramming needs.
Main Results:
- Overall complication rates were comparable: 5% for VVI and 5.3% for DDD systems.
- Specific complications like lead displacement, infection, and muscular stimulation showed no significant difference between the groups.
- Urgent reprogramming was required in 9% of VVI and 8% of DDD systems.
Conclusions:
- Dual chamber pacing does not present an increased complication risk compared to single chamber pacing.
- Both VVI and DDD systems demonstrate acceptable safety profiles.
- Findings support the continued use of dual chamber pacing when indicated.
