Can propafenone hydrochloride tablets treat premature beats?

　　Premature beats refer to premature contractions. Propafenone hydrochloride tablets are commonly used to treat premature contractions. Specific details are as follows:

　　Premature contractions typically refer to abnormal heartbeats that suddenly occur after a normal heartbeat. If accompanied by organic heart diseases such as coronary heart disease or heart failure, symptoms such as angina, chest tightness, and shortness of breath may appear. These can potentially trigger malignant arrhythmias like ventricular tachycardia or ventricular fibrillation, which may even be life-threatening. Propafenone hydrochloride tablets are typically an antiarrhythmic medication that reduces myocardial excitability and slows heart rate. It can also prolong the duration of the action potential and effective refractory period, thereby slowing conduction. This drug is commonly used to treat symptomatic supraventricular tachycardia or premature contractions, effectively relieving discomfort.

　　Medications should be taken under a doctor's guidance; self-medication should be avoided to prevent adverse effects on the body. During treatment, attention should be paid to dietary adjustments—spicy and greasy foods such as chili peppers and hot pot should be avoided. Adequate rest is important, and strenuous exercise should be avoided.
