These include how to best measure successful therapy and what is the optimal heart rate. Current guidelines define adequate rate control in AF as maintenance of the ventricular rate response between 60 and 80 beats per minute at rest and 90 and 115 beats per minute during moderate exercise.1 However, no controlled clinical trials have validated these values for preventing all-cause cardiovascular morbidity or mortality and such recommendations may be flawed for a number of reasons including the absence of atrial contraction and altered cardiac haemodynamics, resulting from fast and irregular ventricular rates. Little appreciation has been given so far to the fact that adequate rate control encompasses more than the mere prevention of fast ventricular rates. Few systematic studies explored the effect of rate slowing drugs on chronotropic competence in AF or define upper limits of the appropriate ventricular rate response during exercise. The effect of excessively irregular rhythm is rarely acknowledged in practice as an important constituent of effective rate control. Reference: 1.
