Abstract

Echocardiography is playing an increasing role in patient selection for cardiac resychronization therapy (CRT). The most frequently used techniques for evaluating inter- and intraventricular dyssynchrony are standard echocardiography and tissue Doppler imaging (TDI). Whether these techniques give concordant results is unknown. We studied 44 patients with a left ventricular ejection fraction of 20 ms. Parameters using Sm(p) were highly variable with poor reproducibility, making them unsuitable for evaluating dyssynchrony. In conclusion, our study indicates that there is poor agreement between standard echocardiography and TDI for diagnosing dyssynchrony.
