“…Atrial standstill and sino-ventricular rhythm were observed in four animals (S1, S2, S3 and S5). These findings were reported in cats with hyperkalaemia (Norman et al, 2006;Hall et al, 2010;Spalla et al, 2014). The electrocardiogram of the animal S2, is depicted in Fig.…”

“…As the serum potassium concentration increased, there was a depression of the sino-atrial node, which results in a junctional or ventricular rhythm. This could be considered as preagonal and followed by ventricular fibrillation and asystole (Spalla et al, 2014).…”

Hyperkalaemia is a life-threatening electrolyte imbalance because it affects cardiac conduction and can lead to fatal arrhythmias if left untreated. The present study describes the occurrence of hyperkalaemia in cats and the electrocardiographic changes associated with this electrolyte imbalance. Hyperkalaemia was identified in 83.33 per cent of the study group subjects. Acute kidney injury and obstructive uropathy were the main clinical conditions associated with it. Electrocardiographic findings in hyperkalaemia in different cats under study included peaked T waves in lead II and the precordial lead CV6LL, atrial standstill and sino-ventricular rhythm, normal sinus rhythm, ventricular tachycardia, first-degree atrio-ventricular block, bradycardia, sinus tachycardia, and atrio-ventricular dissociation. Electrocardiography should always be performed in cases suspected of electrolyte imbalances, particularly hyperkalaemia, so as to identify any fatal arrhythmias and initiate treatment at the earliest.
