Atrial tachycardia (AT)
Which are the symptoms?
This condition causes palpitations and heart fatigue.
Atrial tachycardia can either be caused by a re-entry mechanism or by an amplified ectopic focus. In general, atrial re-entry tachycardia is triggered by a premature atrial pulse and is paroxysmal in nature, whereas 'automatic or focal tachycardia' is permanent and does not require an extraneous pulse to trigger.

How is it treated?
Transcatheter ablation using fluoroscopic or non-fluoroscopic techniques is the treatment of choice.
