Non ischemic cardiomyopathy and low burden of scar as revealed by an ECG-score: No need for a defibrillator in special patients after cardiac resynchronisation? Grett M, Trappe HJ Department of Cardiology and Angiology University of Bochum, Germany

the modified Selvester-ECG-score (MSES) changes in QRS-complex correlate with the extend of myocardial scar estimation of scar by Selvester-Score shows high correlation with autopsy-measured myocardial infarct size Selvester-Score was modified to deliver information in patients with conduction defect and non ischemic cardiomyopathy

MSES as a prognostic tool higher MSES correlates with greater risk for adequate ICD-therapies Strauss, D.G., Poole, J.E., Wagner, G.S., Selvester, R.H., Miller, J.M., Anderson, J., Johnson, G., McNulty, S.E., Mark, D.B., Lee, K.L., Bardy, G.H., Wu, K.C. (2011). An ECG index of myocardial scar enhances prediction of defibrillator shocks: an analysis of the Sudden Cardiac Death in Heart Failure Trial. Heart Rhythm 8 (1), 38-45 lower MSES predicts reverse remodeling by CRT Sweeney, M.O., van Bommel, R.J., Schalij, M.J., Borleffs, C.J., Hellkamp, A.S., Bax, J.J.

MSES as a prognostic tool higher MSES correlates with greater risk for adequate ICD-therapies lower MSES predicts greater reverse remodeling by CRT combining these findings with being convinced that reverse remodeling reduces the risk for sustained VT and the belief in a classic model of scar as a substrate and ischemia as a trigger for VT lead to our study
