The influence of ectopic activity to the re sult of atrial ectopia surgical treatment

The efficacy analysis of focal catheter ablations was performed in 123 patients with the various forms of atrial ectopic arrhythmias in dependence of initial ectopic activity degree. The patients with ectopic activity level less than 6.3% per day had the noneffective outcomes risk increase in 4.5 times and the operation time elongation on 55.9 percent. At the same time risk of development of the ectopic complications (atrial fibrillation, atrial dilatation) was below in 2 and 3 times respectively, than in the patients with more often ectopia. Thus, the patients with stable ectopic activity more than 6.3% per day are the optimum candidates for focal atrial catheter ablation perfomance.
