RESUMEN
<p><b>OBJECTIVE</b>To evaluate the left ventricular systolic asynchrony in patients with uremic myocardiopathy (UM) using tissue synchronization imaging (TSI).</p><p><b>METHODS</b>Ultrasound system with TSI and Q-analyze software were used. Thirty-five patients with UM were enrolled in the study,and thirty normal subjects were included as the control group.</p><p><b>RESULT</b>The total and mean time to peak velocity (Tc) corrected by the heart rate of all segments in UM group were longer than those in the control group (P<0.05), and the time to peak velocity of most segments in UM group was also longer (P<0.05). Delayed time to peak velocity was found in 175 (175/420) segments in UM group and left ventricular systolic asynchrony was detected in 65.7% (23/35).</p><p><b>CONCLUSION</b>TSI can detect the ventricular systolic asynchrony in patients with uremic myocardiopathy and provide reliable parameters for clinical management.</p>
