Unifying Algorithm for Mechanistic Diagnosis of Atrial Tachycardia
Tachycardia, Atrioventricular Nodal Reentry
Tachycardia, Ectopic Atrial
Adenosine-sensitivity (termination or transient slowing/suppression) in response to adenosine was 100% sensitive and specific for identifying focal AT mechanisms due to triggered activity or automaticity, respectively. Absence of adenosine effect on focal AT identifies tachycardia due to microreentry.
