Abstract

Refrakter periyodun ve iletim hızının heterojenitesi re-entran aritmilerin temel mekanizmasını
oluşturur.Ventriküler refrakteritenin heterojenitesini gösteren indekslerden biri yüzey elektrokardiyogramından
(EKG) elde edilen QT dispersiyonudur. QT dispersiyonunu hesaplamada en çok
kullanılan yöntem 12 derivasyonlu EKG’de en uzun ve en kısa QT intervalinin farkının alınıp hıza
veya kullanılan derivasyon sayısına göre düzeltilmesidir.Anormal olarak artmış QT dispersiyonu
bazı hastalıklarda (kardiyak ve nonkardiyak) aritmik ölüm riskini artırır. QT dispersiyonu bazı ilaçların etkinlik ve proaritmik potansiyeli hakkında da fikir veren basit,pratik,ucuz bir parametredir.
Bu derlemede QT dispersiyonunun ölçümü, yorumu, klinik önemi ve diğer bir kavram olan P dispersiyonu
anlatılmıştır.
