Conclusion Our findings indicate decreased iCEB values in PCOS patients compared to the healthy controls suggesting that PCOS patients may be prone to increased risk of malignant arrhythmias and sudden death iCEB may be a more useful parameter in explaining the arrhythmic risk, as other parameters provide information only about the repolarization of the action potential

Abstract

Background/Aim: Polycystic ovary syndrome (PCOS) is the most common endocrine abnormality of reproductive-aged women and increases the risk of cardiovascular disease. In previous studies, deteriorations in both atrial and ventricular parameters in electrocardiography (ECG) were detected. In this study, we aimed to investigate and compare the new ECG parameter, index of cardioelectrophysical balance (iCEB) between PCOS and the control groups and to reveal the relationship between this parameter and the hormonal status in PCOS patients. Materials an methods: This prospective study included 39 patients with PCOS and 40 healthy controls. The heart rate, PR interval, QRS interval, QT interval, QTc interval, iCEB, and iCEBc were measured in 12-lead ECGs. Results: In electrocardiographic parameters, the QRS interval was significantly longer in the PCOS group compared to the control group. iCEB and iCEBc values were found to be significantly shorter in patients with PCOS compared to the control group. In the univariate correlation analysis, a negative correlation was found between serum testosterone and iCEB, and iCEBc. Conclusion Our findings indicate decreased iCEB values in PCOS patients compared to the healthy controls suggesting that PCOS patients may be prone to increased risk of malignant arrhythmias and sudden death iCEB may be a more useful parameter in explaining the arrhythmic risk, as other parameters provide information only about the repolarization of the action potential

Özet

Amaç: Polikistik over sendromu (PKOS), üreme çağındaki kadınlarda en sık görülen endokrin anormalliktir ve kardiyovasküler hastalık riskini artırmaktadır. Daha önceki yapılan çalışmalarda elektrokardiyografide (EKG) hem atriyal hem de ventriküler parametrelerde bozulmalar saptanmıştır. Biz de bu çalışmada, PKOS hastaları ve sağlıklı kontrol grubu arasında yeni bir EKG parametresi olan kardiyak elektrofizyolojik denge indeksini (iCEB) karşılaştırmayı ve PKOS hastalarında bu parametre ile hormonal durum arasındaki ilişkiyi ortaya koymayı amaçladık. Gereç ve yöntem: Bu prospektif çalışmaya PKOS'lu 39 hasta ve 40 sağlıklı kontrol dahil edildi. 12 derivasyonlu EKG'lerde kalp hızı, PR aralığı, QRS aralığı, QT aralığı, QTc aralığı, iCEB ve iCEBc ölçüldü. Bulgular: Elektrokardiyografik parametrelerde QRS aralığı kontrol grubuna göre PKOS grubunda anlamlı olarak daha uzundu. PKOS'lu hastalarda iCEB ve iCEBc değerleri kontrol grubuna göre anlamlı olarak daha kısa bulundu. Tek değişkenli korelasyon analizinde serum testosteron ile iCEB ve iCEBc arasında negatif korelasyon bulundu. Sonuç: Bulgularımız, sağlıklı kontrollere kıyasla PKOS hastalarında azalmış iCEB değerlerine işaret etmekte olup, PKOS hastalarının malign aritmi ve ani ölüm riskinde artış olabileceğini düşündürmektedir. Daha önceden çalışılan EKG parametreleri sadece aksiyon potansiyelinin repolarizasyonu hakkında bilgi sağladığından, depolarizasyon ve repolarizasyon dengesini ifade eden iCEB aritmik riski açıklamada daha faydalı bir parametre olabilir.
