Rate control is not inferior to rhythm control
| The first 150 words of the full text of this article appear below. |
Atrial fibrillation is the commonest sustained tachyarrhythmia encountered
in clinical
practice.1 With an
ageing population and improved survival of patients with cardiac disease its
prevalence continues to
rise.2 It is
associated with a doubling of overall morbidity and mortality from
cardiovascular
disease3 and is the
most common cause of embolic
stroke.4 Restoring
sinus rhythm holds the theoretical advantage of reducing the risk of
thromboembolism and need for anticoagulation and improved haemodynamics and
quality of life. However, most current anti-arrhythmic drugs have limited
efficacy and several side effects. With the use of anti-arrhythmics and serial
electrical cardioversion for early relapse up to 53% of patients are in sinus
rhythm at one year,5
but only 25% remain so at five
years.6 Considerable
controversy therefore exists as to whether rhythm or rate control is the more
appropriate management for most patients with persistent atrial fibrillation.
Five recent trials have looked specifically at this
