Effects of caffeine on potassium currents in isolated rat ventricular myocytes
No === Rapid exposure of cardiac muscle to high concentrations of caffeine releases Ca 2+ from the sarcoplasmic reticulum (SR). This Ca 2+ is then extruded from the cell by the Na +/Ca 2+ exchanger. Measurement of the current carried by the exchanger ( I Na/Ca) can therefore be used to estimate of t...
