Rhythm control in atrial fibrillation

The advice on rate control being as good as rhythm control is now outdated – it comes from the days before catheter ablation could be used, which meant that the disadvantages of rhythm control drugs (which predispose to ventricular arrhythmias and sudden death) balanced out the advantages of being in sinus rhythm. Since this is no longer the case, rhythm control is now advised as the preferred goal for most patients, especially younger patients and those with limiting symptoms. However, catheter ablation is less likely to be successful in longstanding persistent AF or patients with advanced structural heart disease.
