The following are the major diseases or complications that may be contributed to by hyperkalemia (excess potassium):
Cardiovascular system (I00-I99)
- Cardiac arrhythmias (possibly ventricular arrhythmias, especially ventricular extrasystoles (VES) and ventricular tachycardia, which may progress to ventricular fibrillation).
- Cardiac arrest
- Sudden cardiac death (PHT)
Psyche – nervous system (F00-F99; G00-G99)
- Paralytic symptoms
Symptoms and abnormal clinical and laboratory findings not elsewhere classified (R00-R99)
- Marked bradycardia secondary to AV block II° or III°.
- Diarrhea (diarrhea)
- Paresthesias (sensory disturbances; in this case: Tingling in extremities, furry sensation of the tongue).
Further
- Muscle twitching
- Increased mortality (death rate) from myocardial infarction (heart attack):
- Increased 13.4% if a value of at least 5.0 mEq/l was measured only once
- 16.2% increased when hyperkalemia was measured twice
- 19.8% elevated when a value of at least 5.0 mEq/l was reached at least three times
