RODULFO GARCIA, Maikel; CASTELLANOS TARDO, Juan Ramón; REYES SANCHEZ, Raúl  e  TORRALBAS REVERON, Fredy Eladio. Atrial fibrillation after cardiovascular surgery with extracorporeal circulation. MEDISAN [online]. 2012, vol.16, n.4, pp. 513-518. ISSN 1029-3019.

A descriptive and cross-sectional study was carried out in 84 patients who developed new-onset atrial fibrillation after 300 surgeries with extracorporeal circulation performed at the Heart Center of "Saturnino Lora" Provincial Teaching Hospital in Santiago de Cuba, from January 2011 to January 2012. In the series the most affected were those older than 60 years (60,7 %) with an increasing frequency as age advanced. There was predominance in male sex and smoking habit (79,0 %). History of hypertension, mitral valve intervention, anoxic arrest time longer than 60 minutes were the most remarkable factors. Although this arrhythmia was diagnosed at different times after surgery, in 48,8 % it occurred in the first 24 and 48 hours.
