Clinical implications
Observation of Δheart rate and early recurrence of AF are simple and
noninvasive, and prediction of DHF after catheter ablation may be useful
for safe peri-procedural management. If Δheart rate is low, close
observation of symptoms is needed in the early phase (within 2 days)
after the procedure. Additionally, quick management of early recurrence
of AF, such as antiarrhythmic agents and electrical cardioversion, is
taken into consideration in the late phase (≥ 3 days) after the
procedure.
