Mean peak left ventricular tissue velocities at baseline and follow up

Site	Timing of measurement	Baseline velocity (cm/s)	Short term follow up (cm/s)	Long term follow up (cm/s)
Data are mean (SD).
IVC, isovolumic contraction; IVS, interventricular septum; LVFW left ventricular lateral free wall; SYS, main systolic tissue velocity peak.
