Why the study?

Does the Medtronic 6961 transvenous atrial lead provide reliable electrophysiological performance and prevent electrode dislocations in patients requiring atrial sensing and/or pacing?

Key Points

To assess the clinical and electrophysiological performance of the Medtronic 6961 lead in transvenous atrial pacing and sensing.
Used the Medtronic 6961 lead in 14 patients for atrial pacing/sensing.
Measured P-wave amplitude, stimulation threshold, and electrode resistance over four weeks post-insertion.
Conducted observations for 4 to 11 months without electrode dislocations.
Mean P-wave amplitude decreased significantly from 4.9 mV to 309 mV after one week.
Stimulation threshold was 0.9 V after one week, with small subsequent decreases observed.
No complications or electrode dislocations occurred during the observation period.

Structured PICO

Does the Medtronic 6961 transvenous atrial lead provide reliable electrophysiological performance and prevent electrode dislocations in patients requiring atrial sensing and/or pacing?

Population

14 patients requiring transvenous atrial sensing and/or pacing

Intervention

Medtronic 6961 transvenous endocardial atrial lead

Outcome

Electrophysiological parameters (P-wave amplitude, stimulation threshold, electrode resistance, P/QRS-ratio) and electrode dislocations over 4 to 11 monthssurrogate

The Medtronic 6961 transvenous atrial lead demonstrates reliable electrophysiological performance and stability without dislocations, making it a promising option for atrial pacing.
