Outcome:
1. Acute: 83.7% achieved acute termination of the flutter
during the ablation, and the rest required electrical cardioversion to
achieve sinus status at the end of the ablation. The recurrence-free
survival rate was not significantly different based on acute termination
status (p = 0.11), as mentioned in Figure 2 . Acute termination
and lack of inducibility are the common standards to determine success
in the EP lab, particularly for reentrant arrhythmia[8,9,10] . The most important finding is that the index
macroreentrant arrhythmia’s termination does not predict recurrence-free
survival. Lack of inducibility is not an indicator of recurrence-free
survival is another significant finding as it is commonly used as an
endpoint for ablation.
