Backgrounds: The right insular cortical stroke is believed to have arrhythmogenic potential such as secondary atrial fibrillation (AF). P wave-triggered signal-averaged electrocardiogram (SA-ECG) can reveal the wave dispersion which associated with risk of AF in future. However, there has been no relevant clinical study and we investigated after involving insula. Methods: We recruited acute patients consecutively, who admitted from February 2012 October 2013 took routine work-up SA-ECG. Patients had on admission were excluded. SA-ECG was followed up two years onset. Significant P-wave defined ‘P-wave duration (PWD) >125ms for predictor future risk. analyzed difference between cortex lesion other stroke. Results: A total 252 subjects enrolled 49 among them involvement. Follow available 69 patients. In period, longer than (154.0+29.6 vs. 133.5+26.5 ms, p<0.001). involvement, prolonged period shortened follow (n=17, 164.5+35.2 131.7+22.3 p=0.003). did not show interval change. During observation occurred more frequently (33% vs 17%, p=0.01). Conclusion: Our data suggest that increased transiently this might explain development shortly
