Noncompensatory Sinus tachycardia

Noncompensatory Sinus Tachycardia

Sinus tachycardia is a relatively common medical condition estimated to affect up to 2% of the general population. It is characterized by a heart rate that is faster than normal while the rhythm remains regular.

Noncompensatory sinus tachycardia is a special type of sinus tachycardia in which the heart rate is faster than 100 beats per minute and is not associated with any other medical condition. It can have many causes, ranging from normal physiological conditions to psychological stress. It can also occur as a side effect of certain medications.

Symptoms of Noncompensatory Sinus Tachycardia

The most common symptom of noncompensatory sinus tachycardia is a rapid and irregular heartbeat. Other symptoms can include:

  • Lightheadedness or dizziness
  • Shortness of breath
  • Chest pain
  • Palpitations
  • Fatigue
  • Headache

Causes of Noncompensatory Sinus Tachycardia

Noncompensatory sinus tachycardia can have a number of different causes:

  • Stress, anxiety, or fear
  • Exercise
  • Certain medications, such as beta blockers and calcium channel blockers
  • Electrolyte imbalance
  • Caffeine, nicotine, or other stimulants
  • Hormonal imbalances
  • Heart disease or other cardiac conditions
  • Respiratory infections or other respiratory conditions
  • Thyroid disorders

Diagnosis of Noncompensatory Sinus Tachycardia

Noncompensatory sinus tachycardia is usually diagnosed through a physical exam, blood tests, and other tests such as an electrocardiogram (ECG), echocardiogram, or an exercise stress test. Your doctor may also ask you about any medications you are taking, your activities, and how you are feeling to help determine the cause.

Treatment of Noncompensatory Sinus Tachycardia

The treatment of noncompensatory sinus tachycardia depends on what is causing it. In some cases, no treatment is needed. In others, lifestyle changes or medications might be used. Your doctor might recommend increasing your physical activity, reducing caffeine intake, and reducing stress and anxiety.

In cases where the condition is caused by a medication, your doctor may recommend stopping the medication or changing the dosage. In cases where the underlying cause is another medical condition, such as a heart condition, thyroid disorder, or electrolyte imbalance, it may be necessary to treat the underlying condition in order to alleviate the symptoms of noncompensatory sinus tachycardia.
