Can provoke cardiac arrhythmias - called proarrhythmic.
Side effects, such as fatigue, shortness of breath, dizziness, and much worse. Rate control medications, though less risky than rhythm control, aren’t without risks, including: Digoxin (Lanoxin ®) is an example of a cardiac glycoside. Cardiac Glycosides, which improve cardiac output, but can also be toxic. Examples includes Diltiazem (Cardizem ®, Tiazac ®) and Verapamil (Calan ®, Covera-HS ®, Isoptin ®) Calcium Channel Blockers, which relax blood vessels and reduce heart workload. Examples include Atenolol (Tenormin ®), Carvedilol (Coreg™), Metoprolol (Toprol XL™, Lopressor ®), and Sotalol (Betapace ®) Beta Blockers, which slow the heart rate and relax the blood vessels. There are three types of rate control medications: 1įounder & CEO, Types of Rate Control Drugs In either case, a decision as to whether to use anticoagulant medication to prevent strokes is considered critical. These studies indicate that unless rate control has not worked, it is less important to aggressively drive patients into a normal sinus rhythm. Using rate control medication avoids subjecting patients to the riskier rhythm control medications. Some studies have suggested that rate control, when combined with anticoagulation, is as good as rhythm control, and may be better because rate control medications are considered safer and are good overall for treating heart disease and coronary disease. 
There have been ongoing discussions in the medical community as to which of two medication approaches-rate control or rhythm control-is best for atrial fibrillation patients. Rate control medication slows the heart rate to generally less than 100 beats per minute by blocking some of the errant electrical signals in the atria and preventing them from being transmitted to the ventricles.
