  • state-of-the-art review

Authors' conclusion

Collectively, these recent developments position AT as a distinct clinical entity within modern electrophysiological practice and support early intervention to improve clinical outcomes.

Study context

Population
Patients with atrial tachycardias (ATs)

Main finding

As reported in the abstract

AT classification
  • Transition from an electrocardiogram-based descriptive characterization to a unified, mechanistic classification distinguishing non-re-entrant, localized reentrant, and macro-re-entrant AT

Further findings

Acute management

Shifting toward a more pragmatic, mechanism-independent approach, with increasing prioritization of early cardioversion over empirical pharmacological therapy in symptomatic patients

Rhythm control

Progressive downgrading of antiarrhythmic drug therapy, accompanied by an expanding role of catheter ablation as the most effective rhythm control strategy

Consensus statement recommendation

Catheter ablation recommended for any symptomatic, recurrent AT irrespective of mechanism embedded in a 10-Point Plan for SMART-AT care
