Glossary Entry: Transvenous Pacemaker Lead

Overview

Definition: A thin, insulated wire that is inserted through a vein and used to deliver electrical impulses from a pacemaker to the heart muscle.

Detailed Description

Types and Variations

Variations: Different lengths and designs are available to accommodate various patient anatomies and pacing needs.

Indications

Common Uses: Used in patients requiring permanent pacemakers for conditions such as heart block or bradycardia.

Insertion and Placement

Procedure: The lead is inserted through a vein into the heart’s right ventricle or atrium, with placement confirmed via fluoroscopy or echocardiography.

Clinical Considerations

Potential Complications

Risks: Complications may include lead dislodgement, perforation, infection, or lead fracture.

Care and Maintenance

Maintenance Requirements: Regular monitoring and follow-up are necessary to ensure lead function and detect any issues early.

Additional Information

Related Devices

Associated Terms: Pacemaker generator, pacemaker programmer, pacing thresholds.

Innovations and Advancements

Recent Developments: Advances in lead materials and design have improved lead longevity and reduced the risk of complications.

Regulatory and Safety Notes

Regulations: Leads must meet regulatory standards for biocompatibility and electrical performance to ensure patient safety.
