Junctional tachycardia
Junctional Tachycardia
Junctional tachycardia (pronunciation: junc-tional tack-ee-car-dee-uh) is a type of tachycardia that originates from the atrioventricular node (AV node) of the heart.
Etymology
The term "junctional" is derived from the word "junction", referring to the point of connection between two things. In this context, it refers to the junction or connection point between the atria and ventricles of the heart, where the AV node is located. "Tachycardia" is derived from the Greek words "tachys" meaning "swift" and "kardia" meaning "heart".
Definition
Junctional tachycardia is a rapid heart rate condition that originates from the AV node, a part of the heart's electrical system. This condition is characterized by a heart rate that is faster than normal, typically over 100 beats per minute.
Symptoms
Symptoms of junctional tachycardia may include palpitations, shortness of breath, chest pain, lightheadedness, or fainting. However, some individuals may not experience any symptoms.
Causes
Junctional tachycardia can be caused by various factors such as heart disease, electrolyte imbalances, certain medications, or excessive caffeine or alcohol consumption.
Diagnosis
Diagnosis of junctional tachycardia is typically made through an electrocardiogram (ECG), which can detect the abnormal heart rhythm.
Treatment
Treatment for junctional tachycardia may involve medications to control the heart rate, procedures to correct the abnormal heart rhythm, or lifestyle changes to manage underlying causes.
