Atrial Fibrillation in A Diarrheic Holstein Dairy Calf

Abstract

Cardiac auscultation of a 10-day-old diarrheic female Holstein dairy calf revealed irregularities in rhythm and absence of 4^th heart sound. Electrocardiogram (ECG) and blood sample were obtained before and after the treatment. Based on ECG and cardiac auscultation findings, atrial fibrillation (AF) was diagnosed. Serum sodium, calcium and magnesium before treatment were significantly lower than their reference ranges and potassium was significantly higher. One day after treating this patient, serum electrolytes were reached to reference ranges and AF was changed to normal sinus rhythm. Based on resolving the AF after treating the patient and correcting the electrolyte imbalances, it can be suggested that electrolyte imbalances were the main cause of the occurrence of AF in the present case.

Diareli Bir Holştayn Buzağıda Atriyal Fibrilasyon

Abstract

10 günlük yaşta diareli dişi bir Holştayn buzağıda kalp oskültasyonu ile ritim düzensizliği ve 4. kalp sesinin noksanlığı tespit edilmiştir. Tedavinin öncesi ve sonrasında elektrokardiyografi (EKG) ve kan örnekleri alınmıştır. EKG ve kardiyak oskültasyon bulguları doğrultusunda atrial fibrilasyon (AF) teşhis edilmiştir. Tedavi öncesinde serum sodyum, kalsiyum ve magnezyum değerleri referans değerlerinden önemli düzeyde düşük olarak, potasyum ise referans değerinden önemli düzeyde yüksek olarak tespit edilmiştir. Bir günlük tedavi sonucunda hastanın serum elektrolitleri referans değerlere ulaşmış ve AF normal sinus ritmine dönmüştür. Bu çalışmada elektrolit dengesizliğinin düzeltilmesi sonucunda hastanın tedavi edilmesi ile AF’nin giderilmesi, elektrolit dengesizliğinin AF’nin oluşumundaki temel neden olarak göstermektedir.
