All three mechanical dyssynchrony criteria were significantly higher in the DM1 group than in healthy subjects: opposing-wall delays in basal inferoseptal to basal anterolateral segments (61.4<!--> <!-->±<!--> <!-->45.3<!--> <!-->msec vs. 18.3<!--> <!-->±<!--> <!-->50.4<!--> <!-->msec, <em>P</em> <!-->&lt;<!--> <!-->0.001, respectively) and in mid inferoseptal to mid anterolateral segments (58.6<!--> <!-->±<!--> <!-->35.3<!--> <!-->msec vs. 42.4<!--> <!-->±<!--> <!-->36.4<!--> <!-->msec, <em>P</em> <!-->&lt;<!--> <!-->0.05, respectively) (Fig. 1), modified Yu index (33.3<!--> <!-->±<!--> <!-->10.1<!--> <!-->msec vs. 28.5<!--> <!-->±<!--> <!-->8.1<!--> <!-->msec, <em>P</em> <!-->&lt;<!--> <!-->0.05, respectively), and most of time-to-peak values, especially in basal and mid anterolateral segments.</p></div><div><h3>Conclusion</h3><p>The existence of an early LV mechanical dyssynchrony using 2D-STE analysis in DM1 patients before the onset of cardiomyopathy represents a perspective for early prediction of sudden heart death.
