Akut Sigara İçiminin Atriyal Uyarı İletimi Üzerine Etkisi

Abstract

Giriş: Akut sigara içiminin sempatik hiperaktiviteyle ilişkili olduğu bilinmektedir. Bu nedenle biz de akut sigara içiminin atriyal uyarı iletimini değiştirip değiştirmediğini araştırmak istedik. Materyal ve Metod: Aktif sigara içimi öyküsü olan sağlıklı 20 sigara tiryakisi çalışmaya dahil edildi. Sigara içimi öncesinde ve 15 dakika sonrasında katılımcıların 12 leadli yüzey EKG'leri 50 mm/sn kağıt hızıyla çekildi. Bulgular: Maksimum ve minimum p dalga sürelerindeki değişim manuel olarak ölçüldü ve bu iki değer arasındaki fark P Dalga Dispersiyonu (PWD) olarak tanımlandı. Bir sigara içiminin ardından kalp hızı anlamlı şekilde artarken, hem maksimum P dalga süresi hem de PWD değişmeden kaldı (sırasıyla 66 ± 5 vs. 72 ± 8 atım/dakika, p< 0.05; 104 ± 10 vs. 105 ± 7 ms, p> 0.05; 38 ± 10 vs. 42 ± 8 ms p> 0.05).Sonuç: Kronik sigara tiryakilerinde akut sigara içiminin tek başına atriyal uyarı iletimini değiştirmediğini bulduk.

Effect of Acute Cigarette Smoking on Atrial Impulse Propagation

Abstract

Introduction: Acute cigarette smoking has been associated with sympathetic hyperactivity. We therefore sought to determine whether acute cigarette smoking alters atrial impulse propagation. Materials and Methods: Twenty healthy smokers with a history of active smoking were included to the study. The 12-leads surface ECG recorded at a pepper speed of 50 mm/s was obtained from all participants before and average 15 minutes after smoking one cigarette. Results: The change in maximum and minimum P wave duration was measured manually and difference between two values was defined as P wave dispersion (PWD). Both maximum P wave duration and PWD remained unchanged while heart rate significantly increased after smoking one cigarette (104 ± 10 vs. 105 ± 7 ms, p> 0.05; 38 ± 10 vs. 42 ± 8 ms, p> 0.05, and 66 ± 5 vs. 72 ± 8 beat/min, p< 0.05, respectively). Conclusion: We found that acute cigarette smoking alone did not alter atrial impulse propagation in chronic smokers
