Understanding Atrial Tachycardia: Symptoms & Treatment

What is Atrial Tachycardia?

Understanding Atrial Tachycardia: Symptoms & Treatment Atrial tachycardia is a type of heart rhythm disorder characterized by an abnormally fast heartbeat originating in the atria, the upper chambers of the heart. It is often accompanied by a rapid heart rate that exceeds the normal range of 60 to 100 beats per minute.

This condition occurs due to abnormal electrical signals in the heart, causing the atria to contract more frequently than usual. Unlike other similar conditions like supraventricular tachycardia and atrial fibrillation, atrial tachycardia is characterized by a regular and organized heart rhythm.

Atrial tachycardia can affect individuals of all ages, including children and adults. It may be sporadic or recurrent, depending on the frequency and duration of the rapid heart rate episodes. While the exact causes of atrial tachycardia are not always known, certain factors such as heart disease, structural abnormalities in the heart, and prior heart surgeries may increase the risk of developing this condition.
