Abstract:Objective To investigate the effect of left bundle branch pacing and right ventricular septal pacing in the treatment of atrioventricular block. Methods One hundred and twenty-one patients with atrioventricular block treated from June 2020 to June 2021 in Shijiazhuang People’s Hospital were selected, and a total of 88 cases were enrolled after screening. They were divided into control group and study group by random number table method, with 44 cases in each group. The control group was given right septal pacing and the study group was given left bundle branch regional pacing. The cardiac function indexes, including left atrial anterior posterior diameter, left ventricular short axis shortening rate, left ventricular ejection fraction, brain natriuretic peptide (BNP) index, and QRS wave group width, and the occurrence of adverse effects in the two groups were compared. Results Three months after surgery, left ventricular short axis shortening rate, left ventricular ejection fraction in the two groups were higher than those before surgery, and left atrial anterior and posterior atrial diameter was lower than those before surgery, and left ventricular short axis shortening rate, left ventricular ejection fraction in study group were higher than those of control group, and left atrial anterior and posterior atrial diameter were lower than those of control group (P<0.05). Three months after operation, BNP levels in two groups were lower than those before operation, QRS wave widths were longer than those before operation, BNP in study group was higher than that of control group, QRS wave width was shorter than that of control group (P<0.05). There was no significant difference in the total incidence of adverse reactions between the two groups (P>0.05). Conclusion Compared with pacing in the right ventricular septum, the left bundle branch region pacing has less effect on cardiac function in patients with atrioventricular block, especially in patients with preoperative heart dysfunction, pacing in the left bundle branch region has more obvious improvement in cardiac function than pacing in the right ventricular septum region, and has significant clinical effect and effectively reduces the occurrence of adverse reactions, which is worthy of clinical promotion and application.
