Abstract

Amaç: Mitral anüler kalsifikasyon (MAK) mortalite
indikatörü olan azalmış kalp hızı değişkenliği, bozulmuş P dalgası dispersiyonu
ve atriyal elektromekanik gecikme ile ilişkili olduğu saptanmıştır. MAK’ın
potansiyel aritmojenik etkileri olabileceğini göz önüne alarak çalışmamızda
MAK’ın kalbin elektrofizyolojisi üzerine etkilerini klasik EKG parametrelerine
ek olarak f(QRS‐T) açısı ve Tp-e/QT gibi yeni aritmojenik idikatörleri
kullanarak araştırmayı amaçladık.

Hastalar ve Yöntemler: Toplam 200 ardışık hasta [n=100
MAK (+) ve n=100 MAK (-)] çalışmaya dahil edildi. Toplanılan tüm veriler ve elektrokardiyogram parametreleri
gruplar arasında karşılaştırıldı.

Bulgular: P Dalgası MAK (+) grubunda, kontrol
grubuna göre anlamlı şekilde uzun izlenmiştir (p<0.001). Düzeltilmiş QT intervali MAK (+) grubunda,
kontrol grubuna göre anlamlı olarak uzun izlenmiştir (p<0.001). Tp-e intervali MAK (+) grubunda,
kontrol grubuna göre anlamlı olarak uzun izlenmiştir (p<0.001). Tp-e/ QT intervali ve Tp-e/ düzeltilmiş QT intervali
oranı MAK (+) grubunda, kontrol grubuna göre anlamlı olarak uzun izlenmiştir (p<0.001). Frontal QRS-T açısı
MAK (+) grubunda anlamlı olarak fazla izlenmiştir (p<0.001).

Sonuç: Çalışmamızda MAK’ın EKG üzerindeki
etkileri değerlendirilmiştir ve literatürde ilk kez MAK’ın kalbin
repolarizasyon parametreleri üzerinde negatif etkileri olduğu saptanmıştır.
