First of all, let’s look at a case: patient Zhang, 28 years old, in the past 2 years, he felt dizzy and weak, mostly when he was active or busy at work, he felt “not enough strength”, his physical examination showed a heart rhythm of 49 beats/min, which was in rhythm, and the rest was not abnormal; the electrocardiogram showed sinus bradycardia, with a heart rate of 48 beats/min; the electrocardiogram was found during the physical examination for the college entrance examination. Sinus bradycardia was found in the electrocardiogram during the physical examination for the college entrance examination, and it was found to be sinus bradycardia in several subsequent physical examinations. Other tests did not show any abnormality. In the process of clinical treatment, we often see some young and middle-aged patients with sinus bradycardia, who are mostly younger than 45 years old and have various symptoms caused by bradycardia, such as dizziness, weakness, and failure of heart rate to rise in time during activity, etc.; however, the conventional examination fails to show that their hearts have organic pathologies. The next step in the treatment of these patients poses a challenge for physicians, as they are all eligible for permanent pacemaker implantation according to current treatment guidelines, but there are many problems: 1. Pacemakers are paced at non-physiological sites, and long-term dependence on pacemakers will have a serious impact on the function of the heart. Recently, we performed cardiac electrophysiological examinations on such patients and found that the function of the cardiac electrical conduction system was normal, but most of them showed cardiac “vagal hyperfunction”. One of the ways in which the vagus nerve functions in the heart is to slow down the heart rate, and its hyperfunction may be one of the causes of chronic bradycardia in these patients. After the ablation procedure, the 24-hour total heart rate, mean heart rate, fastest heart rate, and slowest heart rate of the patients were significantly improved compared to the preoperative period, and the patients’ symptoms were relieved without complications. Although the observation time was short and the number of cases was limited, we saw the hope and prospect of a new treatment method other than pacemakers. To avoid long-term dependence on pacemakers from the middle-aged and young adult stage, our new method of this treatment is more worthy of further research and promotion.
