For all patients with heartburn, tachycardia is not a cause of heartburn-like symptoms. Tachycardia is often not identified due to a lack of testing or the patient's poor language skills, so the diagnosis needs to be made based on symptoms and an electrocardiogram. For patients with tachycardia, the most dangerous is atrial fibrillation, which can lead to stroke or death.
In the US, one-third of all outpatients treated for [congestive heart failure](https://www.withpower.com/clinical-trials/congestive-heart-failure) use β-blockers. Tachycardia secondary to heart failure may be treated with beta blockers, ACE inhibitors, calcium channel blockers, amiodarone, or digoxin. Beta-blockers are preferred over others and may not be necessary in all patients. Patients who do not adequately respond to one of these treatments should be referred for further evaluation.
Around 60 million tachycardia admissions occur in the United States each year. As many as 1 in 5 patients admitted to the emergency department are admitted on account of tachycardia. There is an apparent difference in the age of presentation, with around two-thirds of admissions occurring in patients over 65 years of age, compared with around 15% of admissions in the under 55 age group. A more serious form of tachycardia than supraventricular tachycardia occurs in over 20% of tachycardia admissions.
Tachycardia is a rate that is more than what is normal (usually between 80 and 120 beats per minute). It has been described as being either supraventricular or ventricular. In newborn babies, the rate is between 80 and 100 beats per minute.\n
A variety of underlying conditions can cause tachycardia, including autonomic dysregulation, hypoxia, hyperthyroidism, and metabolic acidosis. Cardiac pathology may cause tachycardia by a variety of mechanisms, including increased cardiac output from the pumping action of the heart, increased cardiac vagal tone, or abnormal heart rate responses to the sympathetic nervous system. Treatment of tachycardia is aimed toward the underlying cause; antiarrhythmia drugs, such as digitalis therapy and beta blockers, and medications with antihyperthyroid effects, such as propylthiouracil, can be useful as adjuncts to appropriate therapy of the underlying root cause.
Exercise-associated tachycardia can have several serious underlying causes. In addition to evaluating for cardiac disease, a patient's history is vital. Symptoms and history must be evaluated to determine the underlying cause.
Older people with tachycardia have many risk factors for complications such as congestive heart failure, pulmonary diseases, and cerebrovascular Disease, and they are in danger of developing these complications over time as heart rate continues to increase. In order to prevent the complications associated with tachycardia, we need to modify lifestyle risk factors in older people like diet, smoking, etc. and to control blood pressure and other related diseases in older people like hypertension and diabetes.
In general, patients with SS use many medications for various medical conditions. More study is necessary to determine if these medications are effective in reducing symptoms.
Although there is a trend toward better improvement with the sham therapy than with placebo therapy, the data do not have sufficient data to identify an effective treatment. The study design did not include a control group.
Treatment in combination is typically used in patients with other medical conditions. In many patients with tachyarrhythmia, antiarrhythmic treatments or antianginal therapy may be accompanied by treatment of symptoms of hypotension, hyperinsulinemia or hypoglycemia or the medication may be used to control electrolyte abnormalities or metabolic conditions. In addition, most patients with tachyarrhythmia will have multiple concurrent chronic conditions. Therefore therapy used in combination with treatment of the other concurrent diseases may have a significant effect on the rate of tachyarrhythmia control.

The data suggest that there are many causes involved in tachycardia which needs to be explored for each patient who presents to the emergency department. However, we recommend that the most important considerations are the patient's history and physical examination.
