Erratum to: Heart Fail Rev DOI 10.1007/s10741-010-9205-3

Unfortunately the third author of the article was listed incorrectly in the original version. The correct name of the third author is Bart W. L. De Boeck (not Bart W. L. DeBoeck).

Moreover, the legends of Figs. 3 and 4 have been swapped. That is, the figures themselves are listed and displayed correctly as 3 and 4 according to their appearance in the text, but their respective explanatory legends are swapped. The correct legends of Figs. 3 and 4 are listed below:

Fig. 3 Bulls-eye plots of the distribution of external myocardial work in the canine left ventricle during normal impulse conduction (atrial pacing) and during asynchronous activation, as induced by RV apex and LV free wall pacing. Simplified fiber stress–fiber length (S–L) relations in regions with normal (red) early (black) and late (yellow) activation are presented. Strain was measured using MRI tagging; stress was estimated from LV pressure and cavity volume and local strain. [17] External work is determined as the area of the S–L loop [40].

Fig. 4 Definition of SRS and ISF, using strain signals from septum and LV lateral wall from a dog with LBBB (same signals as in Fig. 1). The gray part of the curves indicate the diastolic phase, not used for calculation of ISF and SRS.
