Abstract:Objective To investigate the predictive value of fragmented QRS wave for recurrence in patients with hypertrophic cardiomyopathy and atrial fibrillation after catheter ablation. Methods A total of 95 patients with hypertrophic cardiomyopathy and atrial fibrillation who underwent catheter ablation at the Aviation General Hospital from February 2016 to February 2018 were enrolled. All patients were divided into recurrent group (45 cases) and non-recurrence group (50 cases) according to whether there was recurrence after operation. The general data, levels of cardiac function related index, operation time, fluoroscopy time, fragmentation QRS wave and corrected QT interval (QTc) were compared between the two groups, and multivariate Logisitic regression analysis was performed. Results There were no significant differences in the age, gender, paroxysmal atrial fibrillation and atrial fibrillation between the two groups (all P > 0.05). The left atrial diameter of the recurrent group was greater than that of the non-recurrent group, and the difference was highly statistically significant (P < 0.05). The proportion of patients with fragmentation QRS wave and the QTc level in the recurrent group were higher than those in the non-recurrent group, the differences were highly statistically significant (all P < 0.01). Multivariate Logisitic regression analysis found that both fragmentation QRS wave and QTc were risk factors for recurrence after catheter ablation in patients with hypertrophic cardiomyopathy and atrial fibrillation (all P < 0.01). Conclusion Fragmentation of QRS and QTc have high predictive value for recurrence after catheter ablation in patients with hypertrophic cardiomyopathy and atrial fibrillation. It is worthy of clinical application.
