Amaç: Bu çalışmanın amacı, kalp pili implantasyonundan sonraki ilk 12 saat içinde elektrot empedansı, algılama ve uyarı eşiği değerlerindeki erken değişiklikleri değerlendirmektir.Yöntem: Ocak 2024 ile Aralık 2024 tarihleri arasında cihaz implantasyonu yapılan toplam 50 hasta bu prospektif çalışmaya dahil edildi. Elektrot empedansı, algılama amplitüdü ve uyarı eşiği değerleri implantasyondan hemen sonra ölçüldü ve 12 saat sonra tekrar değerlendirildi. İki zaman noktası arasındaki değişiklikler istatistiksel olarak analiz edildi.
Bulgular:İmplantasyondan sonraki ilk 12 saat içinde elektrot empedans değerlerinde anlamlı bir azalma gözlendi (p<0,05). Buna karşılık, algılama amplitüdleri ve uyarı eşiklerinde göreceli olarak stabilite gözlendi ve istatistiksel olarak anlamlı bir değişiklik tespit edilmedi (p>0,05). Hem atriyal hem de ventriküler elektrotlar, algılama veya uyarma etkinliğini etkilemeden benzer empedans düşüşü paternleri sergiledi.
Sonuç: Bu çalışma, kalp pili implantasyonunu takiben ilk 12 saat içinde elektrot empedansında anlamlı bir erken düşüş olduğunu, ancak algılama ve uyarı eşiği değerlerinin stabil kaldığını göstermektedir. Bu bulgular, modern kalp pili ve defibrilasyon elektrotlarının kısa vadede güvenilirliğini doğrulamakta ve cihaz implantasyonunu takiben elektrot parametrelerinin erken izlenmesinin önemini vurgulamaktadır.

Evaluation of Electrode Impedance, Sensing, and Pacing Threshold Changes at 12 Hours After Pacemaker Implantation

Öz

Objective: The aim of this study was to evaluate the early changes in electrode impedance, sensing, and pacing threshold values within the first 12 hours after pacemaker implantation.
Methods: A total of 50 patients who underwent device implantation between January and December 2024 were included in this prospective study. Lead impedance, sensing amplitude, and pacing threshold were measured immediately after implantation and reassessed at 12 hours post-implantation. Changes between the two time points were statistically analyzed.
Results: Lead impedance values significantly decreased within the first 12 hours following implantation (p<0.05). In contrast, sensing amplitudes and pacing thresholds remained relatively stable, and no statistically significant changes were observed (p>0.05). Both atrial and ventricular leads demonstrated similar patterns in impedance reduction without compromising sensing or pacing efficacy.
Conclusion: This study demonstrates that a significant early decrease in lead impedance occurs within the first 12 hours after pacemaker implantation, while sensing and pacing thresholds remain stable. These findings confirm the short-term reliability of modern pacing and defibrillation leads and highlight the importance of early monitoring of lead parameters following device implantation.
