Treatment for physiologic<unk>  involves treating the underlying causes of the tachycardia response. Beta blockers may be used to decrease tachycardia in patients with certain conditions, such as ischemic heart disease and rate-related angina. In patients with inappropriate<unk> , careful titration of beta-blockers, salt loading, and hydration typically reduce symptoms. Patients who are unresponsive to such treatment can undergo catheter ablation to potentially repair the<unk>  node. Acute myocardial infarction<unk>  can present in more than a third of the patients with AMI but this usually decreases over time. Patients with sustained<unk>  reflects a larger infarct that are more anterior with prominent left ventricular dysfunction, associated with high mortality and morbidity. Tachycardia in the presence of AMI can reduce coronary blood flow and increase myocardial oxygen demand, aggravating the situation. Beta-blockers can be used to slow the rate, but most patients are usually already treated with beta-blockers as a routine regimen for AMI. IST and POTS Beta blockers are useful if the cause is sympathetic overactivity. If the cause is due to decreased vagal activity, it is usually hard to treat and one may consider radiofrequency catheter ablation.
