Group	Intraobserver		Interobserver
	ICC (n = 20)	CV (n = 20)	ICC (n = 20)	CV (n = 20)
GLS (%)	0.98	3.35 ± 0.55%	0.97	4.39 ± 0.71%
GCS (%)	0.85	10.85 ± 1.53%	0.92	7.77 ± 1.12%
GRS (%)	0.65	17.65 ± 6.95%	0.86	11.79 ± 4.77%

Values area means ± SD. GLS, global longitudinal strain; GCS, circumferential strain; GRS, global radial strain. ICC, intraclass correlation coefficients; CV, coefficient of variation.
