Figure 1.
The figure shows the respective distributions of the three therapeutic approaches used in the series of 175 patients included in the present cohort retrospective study. The three graphs with stacked layers refer each to one of the three therapeutic modalities adopted: on the left, the transcatheter ablation, involving 74 patients, of whom 40 subjected to simple ablation and 34 with ablation followed by chronic administration of antiarrhythmics, namely IC drugs or sotalol; at the center, the rate control strategy with the use of atenolol (30 cases) or verapamil (30 cases); on the right the rhythm control strategy, with the bar consisting of three layers representing the use of sotalol (seven cases), propafenone (14 cases) and flecainide (20 cases), respectively.
