Atrioventricular reentrant tachycardia
Atrioventricular Reentrant Tachycardia (pronounced as: ay-tree-oh-ven-TRIK-yuh-ler ree-EN-truhnt tak-ih-KAR-dee-uh) is a type of heart rhythm disorder that occurs when a signal travels through an extra pathway from the atria (the upper chambers of the heart) to the ventricles (the lower chambers of the heart). This can lead to episodes of rapid heart rate (tachycardia).
Etymology
The term "Atrioventricular Reentrant Tachycardia" is derived from the Latin words 'atrium' and 'ventriculus' referring to the chambers of the heart, 'reentrant' meaning re-entering, and 'tachycardia' from the Greek 'tachys' (swift) and 'kardia' (heart).
Symptoms
Symptoms of Atrioventricular Reentrant Tachycardia include palpitations, shortness of breath, chest pain, and fainting or near fainting. However, some people with this condition may not experience any symptoms.
Causes
Atrioventricular Reentrant Tachycardia is caused by the presence of an extra pathway in the heart, which is usually present at birth (congenital). This extra pathway allows electrical signals to bypass the atrioventricular node and move from the atria to the ventricles faster than usual.
Diagnosis
Diagnosis of Atrioventricular Reentrant Tachycardia is typically made through an electrocardiogram (ECG), which can detect the abnormal electrical signals in the heart. Other tests, such as an echocardiogram or a stress test, may also be used.
Treatment
Treatment for Atrioventricular Reentrant Tachycardia may include medications to slow the heart rate or prevent episodes of tachycardia. In some cases, a procedure called catheter ablation may be used to destroy the extra pathway and prevent the abnormal electrical signals.
