Abstract

Objective: P-wave dispersion is associated with inhomogeneous and discontinuous propagation of sinus impulses. The aim of this present study was to investigate the impact of P-wave dispersion in children with stable asthma. Methods: In this cross-sectional study, the study group consisted of 20 children (12 boys, 8 girls) with stable asthma and mean age of 7.7 ± 2.0 years. During the study, these patients were treated with low dose inhaled corticosteroids for at least six months. Control group consisted of 20 healthy children matched by same sex and age population. Age, weight, height, echocardiographic values, P-wave maximum duration and P-wave dispersion were compared between asthmatic and healthy children. P - wave duration was calculated in 12-leads of the surface electrocardiography. The difference between P maximum and P minimum durations was defined as P - wave dispersion. The obtained results were compared by independent samples t test and Mann-Whitney U test. Correlations for P- wave dispersion were calculated using Pearson test. Results: P-wave maximum duration is slightly increased in patients with stable asthma (0.092 ± 0.017 ms) as compared with healthy controls (0.083 ± 0.011 ms) (p=0.07). We found significant correlation between P-wave dispersion and age (r=0.40, p=0.01), weight (r=0.41, p=0.008) and height (r=0.41, p=0.008). Conclusion: P-wave maximum duration is slightly increased and P- wave dispersion is correlated with age, weight and height in children with stable asthma.

Özet

Amaç: P dalga dispersiyonu, sinus uyarılarının homojen ve sürekli olmayan yayılımı ile ilişkilidir. Bu çalışmanın amacı stabil astım tanılı çocuklarda P dalga dispersiyonun etkisini araştırmaktır.Yöntemler: Bu enine-kesitsel örneklemli çalışmada, çalışma grubu, stabil astım tanılı, yaş ortalaması 7.7±2.0 yaş olan 20 çocuktan (12 erkek, 8 kız) oluşmaktaydı. Çalışma boyunca bu hastaların profilaktik, düşük doz inhale kortikosteroid tedavilerine devam edildi. Çalışma grubunu oluşturan çocuklar, en az altı aydır inhale kortikosteroid kullanıyorlardı. Kontrol grubu ise aynı yaş ve cinsiyetteki 20 sağlıklı çocuktan oluşmaktaydı. Astım tanılı çocuklarla sağlıklı çocuklar; yaş, kilo, boy, ekokardiyografik parametreler, P dalgasının maksimum süresi ve P dalga dispersiyonu yönünden karşılaştırıldı. P dalga süreleri 12 derivasyonlu yüzeyel elektrokardiyogramdan hesaplandı. Verilerin istatistiksel analizi bağımsız örneklem t testi ve Mann-Whitney U testi ile yapıldı, P dalga dispersiyonunun korelasyonları için Pearson testi kullanıldı. Bulgular: Stabil astımlı çocuklarda P dalgasının maksimum süresi (0.092±0.017 ms), kontrol grubundakilere (0.083±0.011 ms) göre hafifçe artmış olarak bulundu (p=0.07). Ayrıca, P dalga dispersiyonu ile yaş (p=0.01; r=0.40), kilo (p=0.008; r=0.41) ve boy (p=0.008; r=0.41) arasında da belirgin korelasyon saptandı. Sonuç: P dalga maksimum süresi, astımlı çocuklarda sağlıklı çocuklardan daha yüksekti. P dalga dispersiyonu yaş, kilo ve boy ile korelasyon göstermektedir.
