These graphs show the vital parameters along with the liver and renal functions over time. On day 3 after hospitalization, a catheter infection caused sinus tachycardia and increased creatinine and total bilirubin levels. On day 4, an intra‐aortic balloon pump was inserted. As a result, the heart rate decreased, and the liver and renal dysfunctions improved, suggesting an improvement in HF. On day 6, AF occurred, resulting in an abrupt reduction in blood pressure and the progression of liver and renal dysfunctions again in addition to the increase of blood lactate level. The administration of amiodarone did not lead to the recovery of sinus rhythm, and electrocardioversion was performed and stopped the AF. However, the liver enzymes increased significantly, leading to the requirement for mechanical support. On day 12, an extracorporeal ventricular assist device was implanted.
