Abstract: Summary: Heart rate variability (HRV), analyzed by non-linear methods confer prognostic values. HRV of a heart reviving from extracorporeal circulation (EC) has not been elaborated. We applied Multi-scale entropy (MSE) and Detrended fluctuation analysis (DFA) to study the HRV of patients receiving open-heart surgeries needing EC, during which the heart is standstill. Thirty-four patients were enrolled. ECG was recorded continuously. The analyses were categorized by clinical outcomes. HRV of those without major cardiovascular events (No-MACE) significantly decreased in complexity (4.92 ± 2.80 to 2.94 ± 1.87, p
