The danger of premature heart beats depends mainly on the type of premature heart beats, the number of premature beats and the severity of premature beats, and cannot be generalized. In the case of patients with ventricular premature beats, which are of various forms and particularly numerous, they are generally more harmful and may cause cardiac hazards, and patients may have combined heart failure, heart attack, coronary artery disease and other organic heart diseases. Patients should be actively treated with medication to control the number of premature beats and improve clinical symptoms. Patients with no obvious clinical symptoms, without organic heart disease, who only have atrial or ventricular premature heartbeats with a small number of beats during physical examination, usually do not need medication for the time being and can be closely observed. In addition, patients with premature heart beats should pay attention to a regular lifestyle, take care of rest, maintain a relaxed mood, eat or drink less excitatory foods and drinks, and go to a regular hospital cardiology department for regular review.
