  ABSTRACT: Objective: To identify electrocardiographic parameters that predict extent of early improvement in ejection fraction (EF) in patients with stress cardiomyopathy. Methods: We collected baseline clinical, ECG and imaging data and follow up echocardiography data on 30 consecutive patients with stress cardiomyopathy. The relationship between baseline ECG parameters and Delta EF was evaluated by univariate and multivariable analysis. Results: Median EF improved from 35% to 55% (p Conclusion: The number of leads with T wave inversion is negatively correlated with and is an independent predictor of the extent of early improvement of EF in patients with stress cardiomyopathy. Hence the ECG at initial presentation can be used as a simple tool to predict LV function recovery.
