Case report demonstrates reversal of hyperkalemia-induced atrial standstill and restoration of sinus rhythm in a cat, highlighting the efficacy of prompt intravenous therapy.
Hyperkalemia is a life-threatening electrolyte imbalance which influences cardiac conduction and may lead to fatal arrhythmias if left untreated.The present case report describes the electrocardiographic changes associated with hyperkalemia secondary to obstructive uropathy and cystitis in a cat.Atrial standstill and sino-ventricular rhythm, characterized by the absence of P waves on the electrocardiogram, were observed.Management of hyperkalemia was done using intravenous sodium bicarbonate and dextrose, along with treatment of the primary condition.Re-evaluation of the electrolyte levels and electrocardiogram after treatment revealed a reduction in the serum potassium level and normal sinus rhythm.
