Modes of induced cardiac arrest: hyperkalemia and hypocalcemia - Literature review Modalidades de parada cardíaca induzida: hipercalemia e hipocalcemia - revisão de literatura

The entry of sodium and calcium play a key effect on myocyte subjected to cardiac arrest by hyperkalemia. They cause cell swelling, acidosis, consumption of adenosine triphosphate and trigger programmed cell death. Cardiac arrest caused by hypocalcemia maintains intracellular adenosine triphosphate levels, improves diastolic performance and reduces oxygen consumption, which can be translated into better protection to myocyte injury induced by cardiac arrest.
