<unk>  has been treated both pharmacologically and invasively, with varying degrees of success.<unk> , in and of itself, is not indicative of higher rates of mortality, and non-treatment is an option chosen by many if they have minimal symptoms. Some types of medication tried by cardiologists and other physicians include: beta blockers, selective<unk>  node If channel inhibitors (such as ivabradine), calcium channel blockers, and antiarrhythmic agents. Some SSRI drugs are also occasionally tried, as are treatments more commonly used to treat postural orthostatic tachycardia syndrome, such as fludrocortisone. Invasive treatments include forms of catheter ablation such as<unk>  node modification (selective ablation of the<unk>  node), complete<unk>  node ablation (with associated implantation of a permanent artificial pacemaker), and AV node ablation in very resistant cases (creation of iatrogenic complete heart block, necessitating implantation of a permanent artificial pacemaker). However, invasive treatments can also make the symptoms worse.
