Abstract:
A case of six year old male Labrador dog weighing around 33 kg was presented to Teaching Veterinary Clinical Complex, Bikaner with the history of inappetance, lethargy, intermittent cough, respiratory distress and progressing ascites since three months. The dog was treated previously by a local veterinarian for liver failure and not much significant improvement was observed. On clinical examination revealed lethargy, tachycardia and arrhythmia. On lateral chest radiograph revealed enlarged heart with Vertebral Heart Size (VHS) 12.12. Heart sound was gallop rhythms with third heart sound and lung sound was crackled on auscultation. No significant findings were detected on complete blood count and serum chemistry profiles. ECG showed wide P waves, Tall R waves, supraventricular QRS complexes and irregularly irregular R-R intervals with fast rhythms indicating clearly atrial fibrillation and intermittently ventricular premature complexes. The dog was treated with Furesomide @ 2 mg/kg BID, Pimobendan @ 0.25 mg/kg, PO, BID, Enalapril maleate @ 0.5 mg/kg BID and diltiazem (0.5 mg/kg, PO, BID). The dog had marked improvement and the medications are being continued lifelong with monthly reviews.
