Brief Summary : Rhythm disorders are a frequent and potentially serious complication of critical patients in the ICU and postoperative cardiac surgery. In particular, atrial fibrillation (AF) is the most common rhythm disorder in patients admitted to the ICU and is associated with excess mortality during acute circulatory failure. In postoperative cardiac surgery, AF affects 15 to 45% of patients. In addition to hemodynamic effects, AF increases the risk of stroke, bleeding, respiratory or renal failure, and doubles mortality at 30 days and 6 months. In the longer term, the recurrence rate of AF within 1 year after hospital discharge is about 50%. Similarly, other rhythm disorders, supraventricular or ventricular, can be life-threatening in ICU patients. While the incidence and complications of rhythm disorders are well documented during sepsis, cardiogenic shock or after cardiac surgery, there are to our knowledge no data on the frequency and complications of rhythm disorders in patients assisted by VA ECMO. The primary objective is to describe the incidence of supraventricular rhythm disorders in patients assisted by VA ECMO.
