Premature ventricular contractions are one of the most common clinical arrhythmias. Most patients do not have organic heart disease and belong to a benign process. For these patients, psychological treatment is mostly advocated, and anti-arrhythmic drugs are given if necessary. However, there are still a few patients who have frequent ventricular premature beats for a long period of time, combined with significant clinical symptoms. If the heart is full, the contraction rate is very strong and the heartbeat is very heavy, but when the heart is not full, the beat is weak and the heartbeat is not felt. A very obvious feeling is that the patient’s heart is beating very heavily or sometimes very lightly with premature beats, and sometimes it feels like the beat is coming out of the throat, or the stomach is squeezed and stimulated and the epigastrium feels uncomfortable. If the tachycardia continuous heartbeat is very fast, if it is very fast, it affects the filling of the heart, blood pressure drops, and even serious to collapse fainting, losing intuition. The treatment of arrhythmia is generally speaking two types, one type of arrhythmia affects the quality of life, such as sleepless nights, bad work, bad life, although there is no danger, but also must be treated, this situation is more common, see the clinic patients are mostly symptomatic but not dangerous arrhythmia; there is another type of dangerous arrhythmia, once not treated not controlled, resulting in the death of the patient, this kind of This kind of arrhythmia is not felt by the patients, they feel nothing, they do not feel serious, but because of the underlying heart disease, patients with myocardial infarction, ventricular tachycardia for more than half a minute, although they feel nothing, just a little panic, but our doctors consider such arrhythmia is dangerous. If this type of patient is poorly treated with medication or cannot tolerate the side effects of medication for a long time. Radiofrequency ablation is an ideal option. Radiofrequency catheter ablation has made great progress in the treatment of tachyarrhythmias, especially for paroxysmal supraventricular tachycardia and idiopathic ventricular tachycardia. It has been successful in more than 90% of cases, is a minimally invasive procedure, and can be performed 12 hours after the procedure to get out of bed. The procedure and method of ablation of ventricular premature beats are approximately the same as those of ventricular tachycardia, especially in right ventricular premature beats, where single-catheter ablation is used, which is a simple procedure that reduces complications and saves costs. It has a high success rate, few complications, and significantly improves the patient’s symptoms. Our cardiology department has successfully treated many such patients with good clinical outcomes.
