Abstract

Profound myocardial ischemia, incapable of producing necrosis may alter myocardial biochemical processes, ultrastructure and functilon for variable lengths of time after the ischemic process is reversed.This condition has been called the «stunned» myocardium. Disturbance of myocardial function secondary to ischemia may produce electric manifestations indiştinguishable from those of myocardial infarction, In this paper we discussed occurance of myocardial stunning and transient O waves.

Geçici Q Dalgaları Ve Miyokard Örselenmesi

Abstract

Miyokard nekrozuna neden olmayan şiddetli miyokard iskemisi, miyokardda iskemi ortadan kalktıkdan sonra bir süre devam eden biyokimyasal, ultrastrüktürel, fonksiyonel bozukluklara neden olabilir.Bu duruma örselenmiş miyokard adı verilir. İskemi sonucu oluşan miyokard fonksiyon bozukluğu miyokard infarktüsünden ayrılamayan elektriksel görünümlere yol açabilir. Biz bu yazıda miyokard örselenmesi ve geçici © dalgalarının oluşumunu tartıştık.
