Objective: To evaluate paroxysmal atrial fibrillation (AF) prevalence in Indian adults who completed 24-Hour Holter monitoring. Methods: A total of 23,847 patients (36.9 % women) were analyzed for AF duration using a software algorithm. Results: AF was diagnosed in 4153 (17.4 %) patients with a median AF duration of 13 min and 55 s. Conclusion: AF prevalence was high and largely untreated. The short duration of AF episodes indicates a low likelihood of detection during clinical visits, highlighting its potential underestimation in Indian healthcare.
