Cardiac Dyssynchrony Quantitated by Time-to-Peak or Temporal Uniformity of Strain at Longitudinal, Circumferential, and Radial Level: Implications for Resynchronization Therapy

Dyssynchrony indexed by circumferential TUS yields greater CRT benefits than that indexed by TPS-SD, supporting the idea of targeting TUS-measured dyssynchrony as a more informative quantitative measurement in CRT patients.
