Premature ventricular contractions are also called premature ventricular contractions; it is possible to recover from premature ventricular contractions during adolescence, but it also depends on the causes of premature contractions; the causes of premature ventricular contractions can be categorized into physiological causes and pathological causes. 1. Physiological causes: unhealthy lifestyle, tricyclic antidepressant poisoning. Most of the premature ventricular contractions can be cured by adjusting personal lifestyle and stopping the medication. 2. Pathological factors: For example, premature ventricular contractions caused by myocarditis, rheumatic heart disease, hyperthyroidism and delayed repolarization syndrome are usually difficult to be cured. In the case of episodic premature ventricular beats in adolescence, there are usually no obvious symptoms. If ventricular premature beats occur frequently, symptoms such as palpitations (rapid heartbeat, often accompanied by panic), angina, and low blood pressure can occur. Patients need to consult the cardiovascular department of the hospital, identify the cause and cooperate with the treatment under the guidance of the doctor.
