Electrocardiographic assessment and survival of control and LKB1-KO mice. A, representative electrocardiogram showing control mice and LKB1-KO mice at 2, 3, and 4 weeks of age. Control mice presented normal sinus rhythm, whereas LKB1-KO mice presented Afib. Afib occurred in 80% LKB1-KO mice by 4 weeks of age. B, mortality rate of control mice and LKB1-KO mice. Mortality curves were created by the Kaplan-Meier method and compared by the log-lank test. n = 20 in each group.
