Summary

Effects of left atrial pressure-guided ventricular rate changes on cardiac function after atrioventricular node ablation combined with left bundle branch pacing

Detailed description

Effects of left atrial pressure-guided ventricular rate changes on cardiac function after atrioventricular node ablation combined with left bundle branch pacing. For patients with non-valvular atrial fibrillation who received atrioventricular node ablation combined with left bundle branch pacing in our hospital, a left atrial pressure catheter was used to monitor atrial pressure during the operation, and a lower average atrial pressure was obtained by adjusting the pacing frequency of the pacemaker. In a randomized controlled manner, the postoperative echocardiography, cardiothoracic ratio, cardiac function, etc. were compared between patients without atrial pressure monitoring and those who received atrial pressure adjustment, in order to clarify the effect of left atrial pressure-guided ventricular rate adjustment on atrioventricular node ablation combined with left bundle Benefit of pacing patients.
