In another group of perfused hearts intracellular calcium and developed pressure were measured.

Therefore the elevation of intracellular calcium cannot be attributed to influx from an external source.

Thus, this process leads to a reduction of intracellular calcium and finally a vasodilation.

Levels of intracellular calcium are regulated by transport proteins that remove it from the cell.

This leads to increased intracellular calcium and is pro-inflammatory.

This enzyme initiates a pathway that leads to a rise in the intracellular calcium.

Fluo-3 is a fluorescence indicator of intracellular calcium (Ca).

This decreases intracellular calcium leading to a reduction in muscle contraction.

The increased intracellular calcium gives a positive inotropic effect.

Thus hypomagnesemia results in an increased intracellular calcium level.
