Tóm tắt

 Post-pacing interval (PPI)-tachycardia cycle length >
 100 ms after entrainment from the cavotricuspid isthmus (CTI) is rare in typical atrial flutter (AFL). Low-voltage areas (LVAs) in the CTI can create conduction blocks or alter wavefront propagation, highlighting their underrecognized role in prolonged PPI in typical AFL.
