“…In the experimental models of potassium infusion, pain was unlikely in the anesthetized animal. In numerous human and dog studies, the onset of congestive heart failure has been associated with an increased heart rate (Malliani and Pagani 1983, Fox 1989, Hasenfuss 1998. Such a process may have occurred in case 1, in which the heart rate was normal initially in the absence of overt signs of heart failure, and then was high despite hyperkalemia when dyspnea was noted together with cardiogenic pulmonary edema.…”

The well recognized cardiac effects of severe hyperkalemia include progressive rhythm and conduction disturbances such as bradycardia, spiked and narrow T waves, widening QRS complex, widening and flattening P wave, disappearance of the P wave, and cardiac arrest. Paradoxically, a heart rate greater than 200 beats/min may coexist with hyperkalemia in some cats. This report describes three cats with moderate to severe hyperkalemia and concurrent rapid heart rate. In each cat, the serum potassium (K(+)) concentration was > or =7.5 mEq/dl with a concurrent heart rate > 200 beats/min. In each cat, nine-lead electrocardiograms demonstrate an absence of P waves and a wide-complex tachycardia. Hyperkalemia should be considered in the differential diagnosis when a feline electrocardiogram demonstrates a wide-complex tachycardia without identifiable P waves.

“…Besides many ventricular arrhythmias, these animals also showed couplets and triplets. These arrhythmias may lead to haemodynamic irregularities (Fox 1989). During the second 24-hour monitoring period, two of these otherwise healthy dogs (mixed-breed and German wirehaired pointer) showed between 884 and 3169 ventricular extrasystoles regardless of the anaesthetic protocol used, indicating that they had a spontaneous tendency to arrhythmias.…”
