Comparison of Echocardiographic and Electrocardiographic Mapping for Cardiac Resynchronisation Therapy Optimisation

Figure 2

Differences in ventricular activation timings in AVD optimisation by echocardiographic methods and ECM. AVD, atrioventricular delay; echo, echocardiographic mapping; echo TVaT, mean of the TVaT obtained based on the optimal AVD obtained through echocardiographic methods; Echo VaT10-90, mean of the VaT_10-90 index obtained based on the optimal AVD obtained through echocardiographic methods; ECM, electrocardiographic mapping; ECM VaT10-90, mean of the shortest VaT_10-90 index obtained for the AVD tested; ECM TVaT, mean of the shortest TVaT obtained for the AVD tested.
