If you have 40,000 premature ventricular beats a day and have no symptoms, it is recommended that you go to the hospital to determine the cause of the premature beats and develop a treatment plan based on the specific situation. Ventricular premature beats 40,000 times a day can be diagnosed by 24-hour ambulatory electrocardiogram (ECG). The total number of beats a day for a normal person is around 100,000 beats a day, and ventricular premature beats 40,000 times a day already belong to frequent ventricular premature beats. Physiological causes of premature ventricular contractions are commonly associated with stress, overwork, excessive alcohol consumption, etc. Pathological causes can be seen in coronary artery disease, rheumatic heart disease, valvular disease, myocarditis, etc., but also in other diseases, such as hyperthyroidism and anemia. Premature beats can be seen in normal people if they are occasional, and regular checkups are sufficient. It is suggested that 24-hour dynamic electrocardiogram should be used to further clarify whether frequent premature beats are accompanied by dysthymia, ternary rhythm, ventricular tachycardia, etc., and further improve the cardiac ultrasound, coronary artery ct, and laboratory tests, etc., so as to clarify the causes of premature beats, and standardize the treatment if necessary. If you have discomfort in the precordial area or find premature beats during physical examination, it is recommended to consult a doctor in time to avoid delaying the condition.
