[Evaluation of left ventricular systolic asynchrony in patients with uremic myocardiopathy using tissue synchronization imaging].
To evaluate the left ventricular systolic asynchrony in patients with uremic myocardiopathy (UM) using tissue synchronization imaging (TSI).



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.



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).



TSI can detect the ventricular systolic asynchrony in patients with uremic myocardiopathy and provide reliable parameters for clinical management.
