The most common type of premature beats are those with a missed heartbeat and a feeling of air blockage. Functional premature beats are mostly caused by emotions and do not require treatment. Organic premature beats, which are commonly caused by coronary artery disease, cardiomyopathy, myocarditis, etc., need to be eliminated through the treatment of the primary cause of premature beats. Premature beats are the most common type of arrhythmia in cardiology. Premature beats can be divided into atrial premature beats, junctional premature beats and ventricular premature beats in terms of morphology. Premature beats can occur in patients with organic heart disease or in normal people. The first step in determining whether a premature beat requires treatment is whether it is caused by an organic lesion or a functional one. Functional premature beats are often caused by emotions, such as tension, anxiety, anger, excitement, etc. This situation only needs to improve the mood, no treatment. Organic premature beats are often seen in patients with coronary heart disease, cardiomyopathy, myocarditis, heart failure, etc., need to treat the primary disease, the primary disease is well, premature beats will disappear. If the premature beats are too many, the discomfort symptoms are obvious, affecting the normal life, can be under the guidance of the doctor, take anti-arrhythmic drugs such as propafenone, mesylate, etc. If the drug treatment is not ideal, can also be radiofrequency ablation surgery.
