Using slew rate to predict lead performance in pacemakers and defibrillators

Evaluating Slew Rate As a Predictor for Optimal Lead Fixation in Transvenous Cardiac Implantable Devices: a Prospective Multicenter Study

Observational Azienda Unità Sanitaria Locale di Parma · NCT06842940

This study is testing if measuring the electrical signals during the placement of pacemakers and defibrillators can help predict how well the devices will work over time.

What this trial studies

This observational study aims to identify reliable electrical parameters measured during the implantation of transvenous pacemakers and implantable cardioverter-defibrillators (ICDs) that can predict optimal lead fixation and long-term performance. It focuses on the correlation between slew rate and other electrical parameters at the time of implantation and their relationship with device performance at a 12-month follow-up. Participants will undergo regular evaluations, including device interrogations at 1 and 12 months post-implantation, as part of routine clinical care. The study seeks to establish whether slew rate can serve as a predictor of long-term lead stability.

Who should consider this trial

Good fit: Ideal candidates include patients undergoing implantation of a transvenous pacemaker or ICD with active lead fixation.

Not a fit: Patients who are pregnant, under 18 years old, or those requiring a new lead position with a previously implanted device may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the reliability of lead fixation in pacemakers and ICDs, potentially improving patient outcomes and device longevity.

How similar studies have performed: While the significance of slew rate in predicting long-term lead stability has been poorly studied, this approach may provide novel insights into lead performance.
