Amaç:
Tp-e, QT dispersiyonu ve bu ikisi arasındaki oranlar ventriküler aritmilerin, özellikle ventriküler prematürite depolarizasyonunun ve ani kardiyak ölümün öngörücü değişkenleri olarak, bu çalışmada küçük kalp sendromu ile tanımlanan hastalarda değerlendirildi.
Yöntem:
Kardiyotorasik oranları hesaplanarak 47’si küçük kalpli, 47’si normal kalpli 94 kadın hasta çalışmaya alındı. QTmaks, QTmin, QRS, JT ve Tp-e intervalleri, Tp-e/QTmaks, Tp-e/QTcmaks, Tp-e/JT ve Tp-e/JTc oranları ölçüldü ve QTcmaks, QTcmin, cQTd ve JTc intervalleri hesaplandı.
Bulgular:
Küçük kalp hasta grubunda cQTd, Tp-e, Tp-e/QTcmaks ve Tp-e/JTc değerleri anlamlı olarak daha yüksekti ve QTcmin değerleri anlamlı olarak daha düşüktü.
Sonuç:
Küçük kalp sendromlu hastalarda Tp-e ve QT dispersiyon değerleri ventriküler repolarizasyonu ve olası bir ventriküler aritmiyi öngörme açısından önemli belirteçlerdir.
Anahtar Kelimeler: Elektrokardiyografi, küçük kalp sendromu, ventriküler repolarizasyon
