When the concentration of extracellular calcium ions is significantly lowered, the calcium ions entering the cardiomyocytes are reduced, which is prone to cardiac arrhythmias such as decreased myocardial contraction and atrioventricular block; when the concentration of extracellular calcium ions is elevated within a certain range, the myocardial contraction is enhanced; and when the concentration of extracellular calcium ions is significantly increased, it can lead to arrhythmias such as atrioventricular block, bradycardia, and even cardiac arrest.
The reference range of normal calcium ion value is 2.25~2.75mmol/L. Calcium ions within the normal range can maintain the normal rhythm of the heart, and the contraction of cardiomyocytes also needs the participation of calcium ions, so calcium ions can affect the conduction and contraction of the heart.
If the concentration of calcium ions in the patient’s body is abnormal, he should consult a doctor in time and have standardized treatment under the guidance of a professional doctor, so as not to delay the condition.
