In our study we compared effect of cardiac resynchronization therapy (CRT) in chronic heart failure (CHF) patients with permanent atrial fibrillation (AF) and patients with sinus rhythm. Special feature of our work was that patients with permanent atrial fibrillation didnt have obligatory ablation of atrio-ventricular node but underwent aggressive rate control to achieve more than 90% of biventricular (BV) complexes. We used 24 hours Holter monitoring because there are data that this method is more accurate than CRT counters.We included 30 patients: 21 patients with sinus rhythm and 9 patients with permanent AF with ejection fraction35%, II-IV NYHA class and wide QRS (120 ms). We examined patients before implantation of CRT and after 6 months.mean NYHA class decreased from III to II. Distance at 6-min walk test increased by 107 m in AF group and by 105 in sinus rhythm group. EF increased by 7% in AF group and by 6% in sinus rhythm group. Mean time of further observation was 2 years (from 10 months to 5 years). There was 1 death (11.1%) in AF group and 3 deaths (15%) in sinus rhythm group (p0,05).CRT is effective in CHF patients with permanent AF and pharmacological rate control if percent of BV pacing is more than 90% on Holter monitoring. |
