beta-blockers: Are they useful in arrhythmias?
... Only in specific settings, such as post-CABG, are they useful in this regard, especially when started preoperatively. The predominant role of beta-blockers in AF is for rate control, by virtue of their AV node-blocking action. For acute control of heart rate, especially in acute myocardial infarctio ...
