Figure 1From: The effect of free-breathing on left ventricular rotational mechanics in normal subjects and patients with duchenne muscular dystrophyMean LV twist of (A) healthy volunteers and (B) patients with DMD for breath-held (BH, solid), free-breathing with averaging (AVG, dashed), and bellows gated (BEL, dash-dotted) methods. BH LV twist is generally higher compared to AVG or BEL, especially at its peak.Back to article page
