Premature beats are a type of cardiac arrhythmia, also known as preterm contractions, which are categorized as atrial and ventricular premature beats, with ventricular premature beats being more common. Arrhythmias include sinus arrhythmia, preterm contractions (premature beats), tachycardia, atrial flutter, fibrillation, and conduction block, among many other types. Premature beats are a relatively mild form of arrhythmia. Atrial premature beats usually do not require treatment, but medication should be given if the patient has significant clinical symptoms or develops tachycardia. Ventricular premature beats are usually asymptomatic and do not require medication, and can be improved by lifestyle modifications. Only when there are symptoms do you need to take medication, commonly used drugs in the clinic include metoprolol and other drugs, if the drug treatment is ineffective, you can choose radiofrequency ablation treatment. If the patient has symptoms of arrhythmia such as palpitations and chest tightness, it is recommended to consult a doctor as soon as possible to make a clear diagnosis and then customize an individualized medical plan.
