The severity of premature ventricular contractions can be determined by electrocardiogram (ECG). For occasional premature ventricular contractions, regular follow-up is sufficient, while frequent premature ventricular contractions, frequent premature ventricular contractions in dysthymia or ternary rhythm, or the combination of underlying cardiopulmonary diseases are more serious and require active cooperation in treatment. An electrocardiogram is the most accurate test for diagnosing premature ventricular contractions, and a 24-hour ambulatory electrocardiogram can be performed if you want to know how many premature contractions occur in a day. Normal cardiac excitation is emitted from the sinus node. Premature ventricular contractions are those in which the excitation of the sinus node occurs before it reaches the ventricles, either from any part of the ventricles or from an ectopic rhythmic point in the septum. Premature ventricular contractions can also occur in normal people and usually do not require treatment and can be followed up. Common physiologic causes of premature ventricular contraction include mental stress, overwork, excessive alcohol consumption, and excessive consumption of strong tea. Pathological causes are often seen in coronary heart disease, coronary heart disease, pulmonary heart disease, valvular disease, myocarditis, etc. There are also some other drug factors that can lead to the occurrence of premature ventricular, such as digitalis drug poisoning. Some patients do not have obvious symptoms when ventricular premature occurs, some patients may have palpitations, chest tightness, panic, cardiac arrest, etc., need to improve the relevant examination in time, such as occasional follow-up can be, such as frequent ventricular premature recommended to consult a professional doctor immediately, follow the doctor’s instructions to take medication, and regular review.
