Diagnostic values of different ECG durations in paroxysmal AF diagnosis

OBJECTIVE: To evaluate the application value of different‐duration electrocardiograms (ECGs) in paroxysmal atrial fibrillation (AF) diagnosis. METHODS: A total of 220 patients with paroxysmal atrial fibrillation diagnosed by 24‐h dynamic electrocardiogram in our hospital from January 2019 to December 2020 were selected as the study subjects. The patients were monitored for 10 s, 5 min, and 24 hr, respectively. The results of the three different‐duration ECGs were compared and analyzed in order to evaluate their paroxysmal AF diagnosis value. RESULTS: Paroxysmal AF was detected in 18 patients (8.2%) with the 10‐s ECG; in 89 patients (40.5%) with the 5‐min ECG; and in 199 patients (90.5%) with the 24‐h dynamic ECG. CONCLUSION: In patients with paroxysmal AF, ECGs with longer detection times had higher detection rates.
