In dogs, there was no correlation (r=0) between potassium blood levels and heart rate (n=15). Hyperkalemia is an elevated level of potassium (K ) in the blood. Normal potassium levels are between 3.5 and 5.0 mmol/L (3.5 and 5.0 mEq/L) with levels above 5.5 mmol/L defined as hyperkalemia. Typically hyperkalemia does not cause symptoms.
