Kalium - Ischämie
Figure 1: Potassium recordings on the surface of an isolated guinea pig papillary muscle in NT-solution. Ischaemic episodes are indicated with time bars. The preparation is stimulated at a frequency of 1 Hz. Surface recordings show the accumulation of potassium during simulated ischaemia with a subsequent decrease of surface potassium (Ks) upon reperfusion. In the presence of nisoldipine potassium rises to a much lesser extent than in the presence of the drug.

Kalium - Ischämie
Figure 2: In a resting papillary muscle recordings of Ks show equal amounts of K-accumulation in the presence as well as in the absence of calcium (+EGTA).
