Abstract

Aim: Index of cardiac electrophysiological balance (iCEB), calculated as QT interval / QRS duration, has been described as a novel indicator for predicting malignant ventricular arrhythmias. Herein, we aimed to explore the relation of coronary collateral circulation (CCC) degree with iCEB and Tp-e / QT ratio.Patient and Methods: Forty-four patients diagnosed with chronic total occlusion (CTO) and 55 healthy subjects in comparable age and sex distribution were included. We classified the CTO patients as good (n= 24) and poor (n= 20) collateral groups. Standard 12-lead standard electrocardiogram (ECG) of all patients was recorded and Tp-Te interval, QT interval, QRS duration, Tp-Te/QT ratio and QT/QRS ratio were measured.Results: Mean Tp-e interval and Tp-e/QT ratio were similar between groups. Also, the groups were comparable regarding iCEB or iCEBc values. In subgroup analysis, there was no relationship between the degree of CCC and ECG parameters including Tp-e/QT ratio, Tp-e and QT/QRS ratio.Conclusion: There was no significant relationship between the iCEB and Tp-e/QT ratio, and the degree of CCC development in patients having CTO.

Özet

Amaç: QT intervali / QRS süresi olarak hesaplanan kardiyak elektrofizyolojik denge indeksi (iCEB), malign ventriküler aritmileri öngörmek için yeni bir gösterge olarak tanımlanmıştır. Burada, koroner kollateral dolaşım (KKD) derecesinin; iCEB ve Tp-e / QT oranı ile ilişkisini araştırmayı amaçladık. Hastalar ve Yöntem: Kronik total oklüzyon (KTO) tanısı olan 44 hasta ile benzer yaş ve cinsiyet dağılımında 55 sağlıklı kişi çalışmaya alındı. KTO hastaları, iyi (n = 24) ve zayıf (n = 20) kollateral grubu olarak sınıflandırıldı. Tüm hastaların 12-lead standart elektrokardiyogramı (EKG) kaydedildi ve Tp-e aralığı, QT aralığı, QRS süresi, Tp-e/QT oranı ve QT/QRS oranları ölçüldü. Bulgular: Ortalama Tp-e aralığı ve Tp-e/QT oranı gruplar arasında benzerdi. Ayrıca, gruplar arasında iCEB veya iCEBc değerleri benzer izlendi. Alt grup analizinde, KKD derecesi ile Tp-e/QT oranı, Tp-e süresi ve QT/QRS oranını içeren EKG parametreleri arasında bir ilişki saptanmadı. Sonuç: KTO'lu hastalarda iCEB ve Tp-e/QT oranı ile KKD gelişiminin derecesi arasında anlamlı bir ilişki saptanmadı.
