Abstract

Objectives: We assessed the effect of obstructive sleep apnea syndrome (OSAS) on cardiac autonomic function with the parameters of heart rate variability (HRV) and heart rate turbulence (HRT) and investigated the frequency of cardiac arrhythmias in patients with OSAS.Study design: Seventy-six patients (27 women, 49 men; mean age 50.6±10.7 years; range 33 to 75 years) with an initial diagnosis of OSAS underwent polysomnography and simultaneous Holter monitoring. The diagnosis of OSAS was based on an apnea-hypopnea index (AHI) of ≥5. The patients were evaluated with time-and frequency-based parameters of HRV, and turbulence onset (TO) and turbulence slope (TS) parameters of HRT. Cardiac arrhythmias were also assessed on Holter monitoring.Results: Fifty-three patients (69.7%) were diagnosed with OSAS, being mild in 25 (47.2%), moderate in 23 (43.4%), and severe in five (9.4%) patients based on the AHI. The patients were divided into two groups as those having an AHI of

Özet

Amaç: Tıkayıcı uyku apne sendromunun (TUAS) kardiyak otonom fonksiyonlara etkisi kalp hızı değişkenliği (KHD) ve kalp hızı türbülansı (KHT) parametreleri ile incelendi ve bu hasta grubunda kardiyak aritmi sıklığı değerlendirildi.Çalışma planı: Çalışmada TUAS öntanısı ile polisomnografi uygulanan 76 hasta aynı anda Holter ile de izlendi. Apne-hipopne indeksinin (AHİ) >=5 olması TUAS olarak tanımlandı. Hastalar KHD analizinin zaman ve frekans temelli parametreleri ve KHT için türbülans başlangıcı (TB) ve türbülans eğimi (TE) parametreleri ile değerlendirildi. Holter izleminde kardiyak aritmi varlığı da araştırıldı. Bulgular: Elli üç hastaya (%69.7) TUAS tanısı kondu. Apne-hipopne indeksine göre, 25 hasta (%47.2) hafif, 23 hasta (%43.4) orta, beş hasta (%9.4) da ağır TUAS olarak sınıflandırıldı. Hastalar AHİ =5 (n=53) olma durumuna göre iki gruba ayrıldı. İki grup KHD parametreleri açısından benzerlik gösterirken, TUAS'li hastalarda TB anlamlı derecede yüksek (p=0.02), TE ise anlamlı derecede düşük (p
