Summary
This study found that permanent endocardial tined leads offer lower stimulation thresholds and good lead stability in pacemaker patients. These leads may be especially useful for patients prone to electrode dislodgement.
Area of Science:
- Cardiology
- Biomedical Engineering
Background:
- Permanent pacemaker implantation requires reliable lead systems.
- Traditional pacing leads can be prone to dislodgement and high stimulation thresholds.
Purpose of the Study:
- To evaluate the safety and efficacy of permanent endocardial tined leads.
- To assess stimulation thresholds and lead stability in a patient cohort.
Main Methods:
- A prospective study of 100 patients receiving permanent endocardial tined leads.
- Acute and follow-up measurements of stimulation thresholds and lead performance were recorded.
Main Results:
- Significantly lower acute mean bipolar stimulation thresholds (0.47 V, 0.85 mA) were observed.
- Excellent lead stability was noted, with no roentgenographic evidence of displacement.
- Three patients required reoperation for lead-related issues, considered secondary to microdislodgement.
Conclusions:
- Permanent endocardial tined leads demonstrate low stimulation thresholds and excellent stability.
- These leads may offer advantages for patients at high risk of electrode dislodgement.
