Objective: The accuracy of E/E′ ratio has not been validated in atrial fibrillation (AF). The objective of this study is to compare the accuracy of the E/E′ ratio averaged over a sample of 10 cardiac cycles and E/E′ ratio obtained in the cycle with the longest RR interval for the estimation of wedge pressure in patients with AF using a simultaneous pulmonary artery occlusive pressure measured with a Swan‐Ganz catheter. Design: Twenty‐four consecutive patients with AF with a Swan‐Ganz catheter were recruited in this study. The majority of patients (92%) were in the early postoperative phase of cardiac surgery. Results: The best sensitivity and specificity was reached with E/E′ ratio in the medial position using the one‐beat method; E/E′ ratio ≥16 with one beat predicts a wedge pressure >15 mmHg with a sensitivity and specificity of 91% and 85%, respectively. Conclusions: Measuring E/E′ ratio using the one‐beat method is a simple and clinically accurate way to estimate wedge pressure in patients with AF.
