Pre-excitation syndrome does not disappear with age. Although pre-excitation syndrome is not an organic heart disease, it is characterized by episodes of tachycardia with heart rate reaching 180-200 beats per minute due to an additional conduction pathway between the atria and the ventricles, which is much faster than the normal atrioventricular (AV) conduction speed. Prolonged episodes can cause ventricular fibrillation, which brings great pain to patients and requires immediate application of effective drugs to control the rapid heart rate. At present, in addition to the application of drug therapy, there are ablation methods, can be treated with pre-excitation syndrome, need to be under the guidance of the doctor comprehensive analysis, choose an effective method of treatment.
