Introduction
Hypokalemia generally refers to low potassium levels in the blood. Cardiac manifestations of hypokalemia usually include arrhythmias, ventricular fibrillation, and heart failure. In addition to these common symptoms, other manifestations such as sinus tachycardia may also occur. Hypokalemia can be treated with medications such as potassium chloride sustained-release tablets, potassium magnesium aspartate tablets, and potassium citrate granules, taken as directed by a physician.
Hypokalemia generally refers to low potassium levels in the blood. Cardiac manifestations of hypokalemia typically include arrhythmias, ventricular fibrillation, heart failure, and others. Specific details are as follows:
1. Arrhythmias
Hypokalemia usually means that the concentration of potassium ions in the blood is below the normal range. When the body lacks potassium, myocardial excitability decreases, leading to arrhythmias. In mild cases, it may manifest as sinus tachycardia or induce atrioventricular block.
2. Ventricular Fibrillation
If hypokalemia is severe and progresses continuously, sudden onset of ventricular tachycardia, ventricular flutter, or ventricular fibrillation may occur.
3. Heart Failure
Hypokalemia can impair myocardial contractile function and may trigger myocardial cell degeneration, necrosis, and even lead to heart failure.
In addition to the above common manifestations, other symptoms such as sinus tachycardia may also occur. Hypokalemia can be treated with medications such as potassium chloride sustained-release tablets, potassium magnesium aspartate tablets, and potassium citrate granules, as prescribed by a physician. If symptoms are significant, prompt medical evaluation is necessary to determine the underlying cause and receive targeted treatment.
