Study type | Observational |
The potassium value is important to prevent cardiac arrhythmias and sudden cardiac death. In patients with renal failure, the potassium value is not stable and tends to raise. Until now there are no data available if the potassium value has a circadian rhythm and if there are individual changes from day to day.

Primary | Potassium rhythm | 15 persons with normal renal function are hospitalized for 24 hours. Blood samples are taken every 2 hours in order to investigate the potassium value. It is repeated with 5 persons after 2 days, with 5 persons after 4 and with 5 persons after 6 days. |
