Hyperkalemia can be initially self-diagnosed by clinical symptoms, but laboratory tests are needed to establish the diagnosis.
1. Cardiovascular symptoms: for example, heart rate slowing down and heart sound weakening, causing arrhythmia, specific changes can be observed through ECG, such as t-wave hyperacuity.
2. Neuromuscular symptoms: such as generalized weakness, muscle pain and numbness of limbs, etc. Once the blood potassium concentration is greater than 7mmol/L, it will induce limb weakness and paralysis, and even respiratory muscle paralysis, resulting in asphyxiation and even death.
3. Other symptoms: nausea, vomiting and abdominal pain, accompanied by azotemia and metabolic acidosis.
Patients with the above symptoms should consult a doctor in time. Hyperkalemia can be diagnosed as hyperkalemia if the concentration of potassium ions in the serum is greater than 5.5mmol/L. The risk of hyperkalemia is relatively high.
The danger of hyperkalemia is relatively large, and it is easy to jeopardize the life and health, and should be treated actively after diagnosis.
