Arrhythmias are treated differently depending on the type of arrhythmia. Some arrhythmias can be treated by undergoing an ablation procedure while other types may require medications, therapies, cardioversion, other catheter procedures, or implanting a device, such as a pacemaker or implantable cardioverter defibrillator (ICD). Be sure to talk to your doctor about what treatments are best for your arrhythmia.
