Medication for Ventricular Arrhythmias

Your doctor sometimes uses medication to restore a normal heart rhythm or prevent stroke in people with ventricular arrhythmias. Medications may be used in combination with other treatments, such as an implantable cardioverter defibrillator.


Antiarrhythmics are sometimes used to help control heart rate and rhythm in people with ventricular arrhythmias. Because some of these medications can instead worsen or trigger symptoms of ventricular arrhythmia, your doctor weighs the benefits against any possible side effects, which may include the development of a new arrhythmia, called proarrhythmia.

Beta Blockers

Beta blockers inhibit the effects of the hormone adrenaline, which causes the “fight or flight” response to stressors, on the heart and blood vessels. This can help slow down your heart rate.
