Potassium deficiency will slow down the heartbeat.
In the early stage of hyperkalemia, the difference between intra- and extracellular potassium concentration increases, and the cells are in a hyperpolarized state, which makes the cell’s autoregulation decrease and manifests as bradycardia; on the other hand, hyperkalemia also affects the conduction system of the heart, resulting in atrioventricular block, and even ultimately inducing ventricular arrhythmia.
In addition to slowing down of heartbeat, hypokalemia may also cause weakness, panic, sweating, dizziness, nausea and abdominal distension. Hyperkalemia should be diagnosed and treated promptly. It is divided into oral potassium supplementation and intravenous potassium supplementation. Principles of intravenous potassium supplementation include: potassium supplementation in urine, concentration not greater than 0.3%, rate not greater than 20 mmol/L, and regular monitoring to avoid hyperkalemia.
The diagnosis of hyperkalemia is mainly based on blood test. If you feel uncomfortable or find abnormal test results, it is recommended to go to the hospital as soon as possible to avoid delaying the condition.
