How Atrial
Tachycardia happens?
Electrical signals in the heart's upper chambers fire abnormally, which interferes with electrical signals coming from the sinoatrial (SA) node --- the heart's natural pacemaker. A series of early beats in the atria speeds up the heart rate. The rapid heartbeat does not allow enough time for the heart to fill before it contracts so blood flow to the rest of the body is compromised.

Presentation
*notes
* SVT is the most common type of arrhythmia in children * More common in women, but may occur in either sex * Anxious young people
* People who are physically fatigued
* People who drink large amounts of coffee
* People who drink alcohol heavily
* People who smoke heavily
*notes
Some people have no symptoms; others may feel:
* Dizziness
* Lightheadedness
* Rapid heartbeat or
"palpitations"
* Angina (chest pain) * Shortness of breath In extreme cases, atrial or SVT may cause: • Unconsciousness
• Cardiac arrest
Symptoms and
Complications of Atrial
Tachycardia
12-lead electrocardiography To help identify, locate, and differentiate atrial tachycardia
*
Holter monitoring - To analyze the onset and termination of atrial tachycardia, identify the
AV conduction block during the episode, and correlate the symptoms to atrial tachycardia
Endocardial mapping - To localize atrial tachycardia Imaging Studies
Chest radiography - To evaluate for pulmonary and cardiac findings Computed tomography (CT) scanning To exclude pulmonary embolism, assess the anatomy of pulmonary veins, and provide images prior to ablative procedure
Echocardiography - To rule out structural heart disease and assess left atrial size, pulmonary arterial pressure, left ventricular function, and pericardial pathology
Evaluation of
Atrial Tachycardia
Many people don't need medical therapy.
