Hyperkalemia poisoning symptoms?

summary

Hyperkalemia, as the name suggests, is a kind of disease related to potassium in human body, which is caused by the change of potassium content in human body. This kind of disease is not a common clinical disease, so it will be difficult to treat. We must be careful with this disease to avoid suffering from hyperkalemia. Hyperkalemia poisoning symptoms? Let's talk about it

Hyperkalemia poisoning symptoms?

(1) inhibition of myocardium: it can weaken the contractility of myocardium, enlarge the heart, weaken the heart sound, and stop the heart in diastole. It also has inhibitory effect, such as indifference, slow reaction, drowsiness and coma.

(2) arrhythmia: almost all kinds of arrhythmias can occur, mainly manifested as sinus bradycardia, conduction block and ectopic arrhythmia, such as ventricular premature beat and ventricular fibrillation. Electrocardiographic findings are valuable in the diagnosis of hyperkalemia. In the early stage, T wave peaked and QT time shortened. With the further aggravation of hyperkalemia, QRS wave widened and amplitude decreased, and P wave morphology gradually disappeared. However, because hyperkalemia is often accompanied by hypocalcemia, acidosis, hyponatremia, etc., the above conditions can also affect the ECG changes, which need to be differentiated.

In hyperkalemia, the activity of sodium pump was enhanced, the active transport of intracellular and extracellular ions was increased (the passive diffusion was relatively reduced), the ratio of potassium sodium exchange was higher than that of hydrogen sodium exchange, hypernatremia, acidosis of extracellular fluid, decrease of intracellular Na + concentration and alkalosis occurred.

matters needing attention

In life, we should pay attention to keep the balance of potassium intake in the body, and carry out regular physical examination; In terms of treatment, we should also actively cooperate with doctors to achieve early recovery.
