Abstract

Objective: Coronary slow flow (CSF) phenomenon is described byangiographically normal coronary arteries with delayed opacificationof the distal vasculature. Several studies have suggested that the interval from the peak to the end of the electrocardiographic T wave(Tp-Te) may correspond to the transmural dispersion of the repolar- ization and that increased Tp-Te interval and Tp-Te/QT ratio are asso- ciated with malignant ventricular arrhythmias. The aim of this studywas to evaluate the ventricular repolarization by using Tp-Te intervaland Tp-Te/QT ratio in patients with CSF. Materials and Methods: This study included 50 CSF patients (40male, mean age 48.6±12.5 years) and 40 control individuals (23 male,mean age 47.8±12.5 years). Tp-Te interval and Tp-Te/QT ratio weremeasured from the 12-lead electrocardiogram. These parameterswere compared in groups.Results: Baseline characteristics of the study groups were comparable.In electrocardiographic parameters analysis, QT and corrected QT weresimilar in CSF patients compared to the controls (357±35.2 vs 362±38.0milliseconds and 419±25.8 vs 430±44.2 milliseconds, all p value >0.05).Tp-Te interval, Tp-Te/QT and Tp-Te/QTc ratio were significantly higherin CSF patients (85±13.7 vs 74±9.9 milliseconds and 0.24±0.03 vs0.20±0.02 and 0.20±0.03 vs 0.17±0.02 all p value

Özet

Amaç: Koroner yavaş akım (KYA) uzak damarların opaklaşmasındagecikme ile birlikte anj iyografik olarak normal koroner arterleri tanımlayan bir fenomendir. Çeşitli çalışmalar elektrokardiyografik Tdalgasının tepe noktasından sonuna kadar olan intervalin (Tp-Te)repolarizasyonun transmural dağılımına uygun olabileceğini ve artmış Tp-Te intervali ve Tp-Te/QT oranının malign ventriküler aritmilerile ilişkili olduğunu ileri sürmüşlerdir. Bu çalışmanın amacı, KYA olanhastalarda Tp-Te intervali ve Tp-Te/QT oranı kullanılarak ventrikülerrepolarizasyonu değerlendirmekti. Gereç ve Yöntem: Bu çalışma 50 KYA hastasını (40 erkek, ortalama yaş48,6±12,5 yıl) ve 40 kontrol bireyi (23 erkek, ortalama yaş 47,8±12,5 yıl)kapsamaktaydı. Tp-Te intervali ve Tp-Te/QT oranı 12-kanallı elektrokar- diyogram ile ölçüldü. Bu parametreler gruplar arasında karşılaştırıldı. Bulgular: Çalışma gruplarının başlangıç özellikleri kıyaslanabilirdi.Elektrokardiyografik parametrelerin analizde, QT ve düzeltilmiş QTkontrollere kıyasla KYA hastalarında benzerdi (362±38,0e karşılık357±35,2 milisaniye ve 430±44,2ye karşılık 419±25,8 milisaniye,tümü için p değeri >0,05). Tp-Te intervali, Tp-Te/QT ve Tp-Te/QTc oranı KYA hastalarında anlamlı olarak yüksekti (74±9,9a karşılık 85±13,7milisaniye ve 0,20±0,02ye karşılık 0,24±0,03 ve 0,17±0,02ye karşılık0,20±0,03, tümü için p değeri
