Comparison of Echocardiographic and Electrocardiographic Mapping for Cardiac Resynchronisation Therapy Optimisation

<div>VaT<sub>10-90</sub> and TVaT values in each patient according to the VVD setting. LVx, intraventricular pacing interval with the left ventricle paced first by x milliseconds; RVx, intraventricular pacing interval with the right ventricle paced first by x milliseconds; SIM, intraventricular pacing interval with the right and left ventricles paced simultaneously; TVaT, total ventricular activation time; VaT<sub>10-90</sub>, ventricular activation time<sub>10-90</sub>.</div>
