Abstract
Atrial tachycardia may be caused by abnormal automaticity, re-entry, or triggered activity. Regardless of the underlying mechanism, it has been observed that, although tachycardia may theoretically arise from any atrial zone, the origin of the arrhythmia is not random, but the ectopic focus or re-entry circuit is frequently located in certain specific areas of the atria [1–4]. It has been suggested that the majority of right atrial tachycardias originate from the crista terminalis (CT) and, accordingly, the term “cristal tachycardia” has been introduced [1–3].
