Sažetak
In patients with chronic atrial fibrillation (AF), control of ventricular rate both at rest and during exercise are necessary as a rapid heart rate may produce variety of clinical symptoms, limit exercise capacity and affect cardiac function. The inforamtion on the optimal ventricular rate control in chronic AF is limited. Recently, the new criteria for ventricular rate control in chronic AF were suggested. In rest, the ventricular rate should ranging from 60 to 80 beats/min, during daily activites from 90 to 115 beats/min, and during submaximal or maximal exercise from 110 to 150 beats/min (individual approache). Control of heart rate in chronic AF may be achieved with drugs or with radiofrequency node ablation or modification. Among various drugs, digitalis is treatment of choice for patients with heart failure and/or left ventricular systolic dysfunction, and for older patients with limited physical activities. The calcium channel blockers and beta-blockers should be preferred in other clinical settings, because they better control ventricular rate during exercise. The choice between these two classes of drugs depends on the associated clinical and medical conditions. The AV node ablation should be reserved for symptomatic patients in whom pharamcological interventions for rate control were ineffective, while the AV node modification is not yet recommended for routine clinicla use.
