مکانیک چرخشی بطن چپ در ابتدای ابتدایی: محدوده مرجع طبیعی و بازتولید کننده مقادیر پیک و زمان به حداکثر مقادیر

Measurements of rotational mechanics and timing to peak values have acceptable reproducibility. Peak twist, twist rate, and early untwist rate values in early infancy are similar to those reported in premature neonates, and higher than those reported in older children. Twist indexed to LV length (torsion) is lower in early infancy than in premature neonates, but higher than in term neonates.
