In most cases, premature beats are not a serious problem in young patients and are considered functional. Young people who are tired, stay up late, drink alcohol, or smoke for a long time may have premature beats, which can be cured spontaneously with lifestyle interventions and do not require special oral antiarrhythmic drugs. If necessary, patients are advised to undergo an ambulatory electrocardiogram to assess the overall 24-hour premature beats and to identify what type of premature beats they are currently experiencing. Some patients may have cardiomyopathy or inflammatory infections or post-traumatic injury, which may cause the appearance of such premature beats secondary to the primary disease, and should be treated primarily for their primary disease. There are also some people who may have ionic disorders or abnormal thyroid function. Such patients may also have premature heart beats, and if they are caused by ionic disorders, the ionic disorders should be corrected, such as the presence of hypokalemia, and patients are advised to take oral potassium chloride extended-release tablets.
