[Effects of an impulse electromagnetic field on calcium ion accumulation in the sarcoplasmic reticulum of the rat myocardium].
By means of an ion-selective electrode, the effect of an impulse electromagnetic field with a 1 ms impulse, 10 Hz frequency, and 1-10 mT magnetic induction on calcium transport was investigated in the presence of potassium oxalate by rat heart homogenates. Prolonged exposure (100 min) to the field produced 70% inhibition of Ca2+ transfer across the sarcoplasmic reticulum. This effect is associated with direct inhibition of Ca(2+)-ATPase.
