Adenosine-Insensitive Focal Atrial Tachycardia. Evidence for De Novo Micro-Re-Entry in the Human Atrium
Tachycardia, Ectopic Atrial
The characteristics of adenosine-insensitive focal AT differ from adenosine-sensitive AT and are consistent with small re-entrant circuits. These data provide evidence that focal re-entry is a mechanism of AT and has an electropharmacologic profile that differs from AT due to automaticity and triggered activity.
