Background:
The time from the initial diagnosis of atrial fibrillation (AF) to the index ablation procedure, known as diagnosis-to-ablation time (DAT), is a modifiable risk factor that is correlated to affect the recurrence of AF. The objective of this meta-analysis was to examine the correlation between diagnosis-to-ablation time and AF recurrence.
Methods:
A systematic search was performed in PubMed, Google Scholar, and Cochrane Library from database inception till June 2024. Studies reporting diagnosis-to-ablation time and its relation with AF recurrence were included. The primary analysis evaluated outcomes segregated by DAT ≤ 1 year versus > 1 year. Random-effects model with the Mantel-Haenszel method was used to evaluate AF recurrence.
Results:
Of the 9177 articles, only 6 observational studies got through the inclusion criteria with a total participant count of 14,862. DAT of greater than 1 year was associated with increased risk of AF recurrence in all the included studies while DAT of ≤ 1 year was correlated with lower risk of AF recurrence (RR, 0.76 (95% CI, 0.73-0.79); P < 0.01). Similarly, DAT of ≤ 3 years was correlated with lower AF recurrence risk (RR, 0.82 (95% CI, 0.79-0.85); P < 0.01).
Conclusion:
Evidence from observational cohorts suggests that the optimum time for ablation in AF patients is less than 1 year and a DAT of ≤ 1 year is linked to 24% lower chances of recurrence in AF patients, compared to DAT of ≥ 1 year.

01:25Correlation between ECG and Cardiac Cycle
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
