Rate-Control Drugs Our review of rate-control drugs explored the comparative effectiveness of beta blockers, calcium channel blockers, digoxin, and other antiarrhythmics in controlling ventricular rate. The 14 included studies varied in terms of the drugs involved, and the lack of multiple studies exploring similar comparisons decreased our ability to quantitatively synthesize their findings. Our findings highlight the lack of definitive data on the superiority of one beta blocker over another or against calcium channel blockers. Our findings underscore the importance of conducting studies comparing the effectiveness, tolerability and safety of different beta blockers and calcium channel blockers and in different patient populations. Table 23 summarizes the strength of evidence for the most commonly used classes of therapies and evaluated outcomes. Details about the specific components of these ratings (risk of bias, consistency, directness, and precision) are available in the Results chapter. For ventricular rate control, most comparisons were evaluated in one small study, resulting in insufficient evidence to support conclusions about comparative effectiveness. Exceptions were as follows: There was low strength of evidence that amiodarone was comparable to the calcium channel blocker diltiazem, and that amiodarone controlled ventricular rate better than digoxin, and there was high strength of evidence for a consistent benefit of verapamil or diltiazem compared with digoxin for rate control. There was insufficient evidence regarding the effect of rate-control therapies on quality of life.

Strict Versus Lenient Rate-Control Strategies Our review identified only one RCT and two observational studies representing secondary analyses of RCTs exploring the comparative safety and effectiveness of strict versus lenient rate- control strategies. Table 24 summarizes the strength of evidence for strict versus lenient rate control and the outcomes of interest. Details about the specific components of these ratings (risk of bias, consistency, directness, and precision) are available in the Results chapter. Across outcomes, data were limited by the number of studies and the imprecision of their findings. We based our findings on the evidence from the one RCT and then evaluated whether the observational studies were consistent or not with these findings. In general, the included studies were consistent in showing no significant difference between strict and lenient rate control with respect to mortality, cardiovascular hospitalizations, heart failure symptoms, quality of life, thromboembolic events, bleeding events, and composite outcomes. However, the RCT differed from the observational studies in showing a statistically significantly lower stroke rate with lenient rate control.
