What is ectopic atrial tachycardia?

Ectopic atrial tachycardia is a rare but serious underlying heart disease caused by the inability of the heart's electrical signals to function properly. This leads to rapid contraction of the heart muscle, which tightens the heart and disrupts normal blood flow to all parts of the body, which can eventually lead to heart failure. One of the causes of adult ectopic atrial tachycardia may be atrial insufficiency, but children may have other factors leading to ectopic atrial tachycardia. This condition is rare in adults but is a common cause of supraventricular tachycardia in children. This condition can cause the heart rate to increase to 250 to 300 beats per minute.


Often there is no root cause for atrial ectopic tachycardia. It can be caused by a viral infection, such as RSV. In some cases, an atrial tumor causes the development of ectopic atrial tachycardia. It is also linked to genetics, and people with congenital heart defects have an increased risk of ectopic tachycardia.


  • In cases of children: loss of mobility, dyspnea, loss of appetite, etc.
  • In cases of adults: chest pain, syncope, palpitations, etc.


Ectopic tachycardia can be effectively treated with medication, although surgery may be needed to correct it in rare cases. In terms of medication, antiarrhythmic drugs can control the heart rate and return it to normal. In very rare cases, catheter ablation may be required to correct problems and restore normal heart rate. This is the last resort when all other treatments fail to improve conditions.
