Right Ventricular Mechanical Dyssynchrony in Hypoplastic Left Heart Syndrome: Correlation with Systolic Function and QRS Duration
Sign Up to like & getrecommendations! Published in 2019 at "Pediatric Cardiology"
DOI: 10.1007/s00246-019-02091-6
Abstract: The single right ventricle (RV) in hypoplastic left heart syndrome (HLHS) often develops systolic dysfunction with time and this affects prognosis. Mechanical dyssynchrony has been reported in HLHS but has not consistently correlated with systolic… read more here.

DOI: 10.1007/s12350-021-02554-5
Abstract: The use of left ventricular mechanical dyssynchrony (LVMD), which has been reported to be responsible for unfavorable outcomes, might improve conventional risk-stratification by clinical indices including QRS duration (QRSd) and systolic dysfunction in patients with… read more here.

DOI: 10.1016/j.cardfail.2019.07.207
Abstract: Background Immune checkpoint inhibitors (ICIs) have revolutionized oncologic care. Myocarditis is an uncommon but frequently fatal complication of ICI use. There is need for improved methods of detection and risk stratification of ICI myocarditis. Both… read more here.

DOI: 10.1016/j.hrthm.2018.01.004
Abstract: BACKGROUND Subcutaneous implantable cardioverter-defibrillator (SICD) shows promise for select patients at risk of sudden cardiac death. However, patients need to pass an electrocardiographic (ECG) screening (ECG-S) test before they can receive an SICD. Predictors of… read more here.

Abstract: BACKGROUND QRS-duration predicts mortality in patients with heart failure and, to a lesser extent, the general population. However, in patients with diabetes, its prognostic significance is unknown. To better understand how QRS-duration relates to mortality… read more here.

Abstract: BACKGROUND Right ventricular (RV) apical pacing is associated with systolic dysfunction and heart failure. Paced QRS duration has been suggested as a predictor of heart failure and left ventricular (LV) systolic dysfunction. However, the effect… read more here.
