Premature beats include ventricular premature beats and atrial premature beats, which are generally less harmful.
1. Ventricular premature beats: also known as ventricular preterm contractions. Ventricular premature contractions can also occur in normal people. There are no specific symptoms and the risk is small. However, in patients with severe organic heart disease, prolonged and frequent ventricular preterm contractions can produce angina or heart failure, and should be treated promptly.
2. Atrial premature beats: also known as atrial pre-systole. Most of them are less dangerous. However, for patients with various organic heart diseases, long-term atrial pre-systole can cause other rapid atrial arrhythmias, which are more harmful.
The risk of premature beats is related to the presence or absence of organic heart disease, as well as the duration and number of premature beats. If more serious premature beats occur, they should be hospitalized and treated according to the doctor’s instructions.
