The severity of more than 1,000 premature beats in 24 hours may be related to ECG examination and concomitant diseases. 1. Electrocardiogram (ECG): To determine the severity of premature heartbeats, the frequency of premature heartbeats is observed on the ECG, whether they are polygenic or monomorphic, and whether they are persistent or recurrent. 2. Underlying disease: If you are old and have had myocardial ischemia, myocardial infarction and other diseases, the situation may be more serious if premature beats occur at this time and there are more premature beats. However, if the young people, the crowd does not have high blood pressure, diabetes, coronary heart disease and other diseases, the heart function is better, and premature beats are mainly in the quiet time, after the movement of premature beats will be reduced or disappeared, at this time there will not be a great harm. If patients with premature beats have underlying diseases, they should actively treat the primary disease, and control risk factors such as blood pressure, blood lipids and blood sugar in order to effectively reduce the risk of premature beats. Physical abnormalities should be timely medical care, clear causes, timely treatment, to avoid aggravation of the situation.
