Abstract Background The impact of the His bundle location and distance from the ablation site on ablation efficacy and complication risk remains unexplored. We determined the correlation between age, height, body mass index (BMI), and the His bundle location, and whether the distance between the His bundle and ablation target (DHIS‐ABL) affects ablation safety and efficacy. Methods Overall, 346 patients with atrioventricular nodal re‐entrant tachycardia (AVNRT) and 96 with atrioventricular re‐entrant tachycardia (AVRT) were retrospectively analyzed. The distance between the His bundle and the coronary sinus ostium (DHis‐CS), the height of the His bundle (HHIS), and DHIS‐ABL were measured. Electrocardiograms were obtained 3 months post‐ablation to assess recurrence and complications. Results Multiple linear regression showed that HHIS was negatively correlated with age in both groups. In AVNRT patients, DHIS‐ABL was associated with age, height, and BMI; DHIS‐CS was only negatively correlated with age. In AVRT patients, there was no significant correlation between the DHIS‐ABL and age, height, or BMI. The recurrence rates in the AVNRT and AVRT groups were 0.9% and 8.7%, respectively. Subgroup analysis showed that patients with DHIS‐ABL ≤ 10 mm had a higher recurrence rate than those with DHIS‐ABL > 10 mm (p = .013). The incidence of third‐degree atrioventricular block (AVB) complications was 0.2%. Conclusions HHIS was negatively correlated with age but not with height and BMI. The DHIS‐ABL correlated with age, height, and BMI in AVNRT patients. A short DHIS‐ABL led to a higher rate of supraventricular tachycardia recurrence; whether this affects AVB risk warrants further studies with larger sample sizes.
