ST segment depression and elevation: A randomized clinical study

Abstract

Objective: The ST segment, an important component of ventricular repolarization, covers the period between the end of ventricular depolarization and the beginning of ventricular repolarization. In dogs, ST segment elevation can be caused by myocardial hypoxia, transmural myocardial infarction, pericardial effusion, while its depression can be caused by myocardial hypoxia, hyperkalemia, hypokalemia, subendocardial myocardial infarction or digoxin toxicity. Within this scope, the retrospective evaluation of the presence of ST segment elevation or depression in cases presented to our clinics with signs of heart and circulatory failure was aimed. Materials and Methods: Electrocardiography (ECG) was performed in 104 dogs of both sexes, different breeds and ages. In all dogs, ECG was performed manually while the dogs were in the right lateral recumbent position. No animal was anesthetized for this procedure and the animals were kept calm. ECG measurements were recorded by the device. Results: Among the 104 dogs, 12 were evaluated within the scope of healthy controls, while ST depression was identified in 3 and ST elevation in 1. ST amplitude was -0.2, -0.21, -0.2 mV in patients with ST depression and +0.15 mV in patients with ST elevation. In healthy dogs, the mean ST amplitude was -0.0325 mV. Conclusion: The findings of this study highlight the importance of electrocardiography in detecting ST segment changes in dogs presenting to clinics. Future research may focus on integrating these findings into the clinical evaluation process and further investigating the effects of these changes on heart and circulatory health.

Öz

Amaç: Ventriküler repolarizasyonun önemli bir bileşeni olan ST segmenti, ventriküler depolarizasyonun sonu ile ventriküler repolarizasyonun başlangıcı arasındaki süreyi kapsamaktadır. Köpeklerde ST segment elevasyonu miyokardiyal hipoksi, transmural miyokard enfarktüs, perikardiyal efüzyon kaynaklı şekillenebilirken depresyonu miyokardiyal hipoksi, hiperkalemi, hipokalemi, subendokardiyal miyokard enfarktüsü veya digoksin toksisitesinden kaynaklanabilmektedir. Bu kapsamda kliniklerimize kalp ve dolaşım yetmezliğine ait bulgularla getirilen olguların ST segment elevasyonu veya depresyonu varlığının retrospektif olarak değerlendirilmesi amaçlandı. Gereç ve Yöntem: Her iki cinsiyetten, farklı ırk ve yaştan 104 köpekte elektrokardiyografi (EKG) işlemi gerçekleştirildi. Tüm köpeklerde EKG işlemi, köpekler sağ lateral yatış pozisyonundayken manuel tutularak gerçekleştirildi. Bu işlem için hiçbir hayvanda anestezi işlemi yapılmadı ve hayvanların sakin kalması sağlandı. EKG ölçümleri cihaz aracılığıyla kaydedildi. Bulgular: 104 köpeğin 12 tanesi sağlıklı kontrol kapsamında değerlendirilirken, 3 tanesinde ST depresyonu ve 1 tanesinde de ST elevasyonu belirlendi. ST depresyonu belirlenenlerde ST amplitüdü -0.2, -0.21, -0.2 mV ölçülürken ST elevasyonu belirlenen hastada ST amplitüdü +0.15 mV şeklinde kayıt edildi. Sağlıklı köpeklerde ST amplitüdü ortalama -0.0325 mV şeklinde bulundu. Sonuç: Bu çalışmanın sonuçları, kliniğe başvuran köpeklerde ST segment değişikliklerinin belirlenmesinde elektrokardiyografinin önemini vurgulamaktadır. Gelecekteki çalışmalarda, bu bulguların klinik değerlendirme sürecine nasıl entegre edilebileceği ve bu değişikliklerin kalp ve dolaşım sağlığı üzerindeki etkilerinin daha iyi anlaşılması için daha fazla araştırma yapılması önerilebilir.
