Design outcomes

Primary

Measure	Time frame
Feasibility (i.e. % of measurements with sufficient quality for analysis) of the following exercise echocardiography variables: - LVEF - Intraventricular dyssynchrony (peak systolic longitudinal strain) - Interventricular dyssynchrony (Inter Ventricular Mechanical Delay) - Mitral regurgitation (regurgitant volume) Day-to-day reproducibility of these exercise echocardiography variables (Blant Altman analysis)	—
