A 9 yo MN blended breed canine, weighing 72 kilos (32.7 kg), offered for a current onset of panting, shortness of breath, weak spot, and syncopal episodes. On bodily examination, the canine’s coronary heart price was 160 bpm, his mucous membranes had been pale, and his pulses had been weak and thready.
An ECG confirmed the tachycardia, together with some extra findings. As a substitute of regular P waves adopted by QRS complexes, the veterinarian noticed an absence of P waves and complexes that had been huge and weird.
