Figure 1 Classification of atrial tachyarrhythmia (AT) on the basis of analysis of stored bipolar electrograms. a) Type I: highly organized AT with discrete deflections of constant morphology, an isoelectric line between signals and a minimal cycle length  200 ms. b) Type II: intermediate type of organization not meeting the definition of type I or type III. c) Type III: disorganized AT with polymorphic deflections, no isoelectric line between signals and a minimal cycle length <200 ms. AS = atrial sense; FD = fibrillation detection interval; FS = fibrillation sense; TF = tachycardia/fibrillation (overlap zone); TS = tachy sense.
