Patient's question:
Brother has been doing temporary jobs in an electronics factory all year round. He never goes home for holidays, always calling to report his safety. But suddenly, he suffered a cardiac arrest due to hypokalemia. At which stage does cardiac arrest occur in hypokalemia?Doctor's answer:
It is necessary to first carefully check for hypokalemia, not only to rule out a decrease in extracellular potassium concentration but also to identify the cause of hypokalemia. Generally, when serum potassium is higher than 3 mmol/L, clinical potassium digestive treatment should be implemented. An electrocardiogram can be checked first. If it is the ST segment of a ventilator, potassium digestive treatment can be implemented, and there will be no more severe consequences of cardiac arrest.
