Disease

What is Supraventricular tachycardia?

It is a heart condition in which there are episodes where the heart beats much faster (between 150 and 250 times per minute) than normal (60 to 100 beats per minute), caused by abnormal atrial signals. Supraventricular tachycardia occurs when the electrical impulses that control the heartbeat have a dysfunction due to a specific trigger such as excessive exercise, stressful periods, or little sleep, although sometimes it can appear without apparent cause. Likewise, there are several potential risks capable of causing it, such as:
  • Alcohol abuse.
  • Cocaine.
  • Methamphetamines.
  • Stress.
  • Heart conditions.
  • Being pregnant.
  • Smoking.
  • Thyroid conditions.
  • Some drugs.
  • Chronic lung disease.
  • Excessive caffeine intake.
Supraventricular tachycardia is classified into three types:
  • Atrial: it is common in patients with heart conditions.
  • Due to reentry of the atrioventricular node: it is the most common, especially in young women.
  • Reciprocal atrioventricular: its incidence is higher in young people of both sexes.

Symptoms

  • Accelerated heart rate that exceeds 100 beats per minute.
  • Exhaustion.
  • Sore chest.
  • Difficulty breathing.
  • Dizziness.
  • Chest palpitations.
  • Fluttering sensation in the neck.
  • Excessive sweating.
  • Loss of consciousness.
If left untreated, this condition can cause chronic heart failure or trigger a heart attack.

Diagnosis and treatment

Once your doctor analyzes your symptoms and clinical history, they will perform a physical examination and request blood tests, an electrocardiogram, a Holter monitor, an echocardiogram, an event monitor, an implantable loop recorder, a stress test, and an electrophysiology test. When the condition is mild, treatment is not usually required, but when the events are recurrent and intense, drugs will be prescribed and procedures such as cardioversion, carotid sinus massage, and vagal maneuvers will be recommended. In more serious cases, it will be necessary to perform a catheter ablation or, as the last option, the implantation of a pacemaker.
