From: Analyzing myocardial torsion based on tissue phase mapping cardiovascular magnetic resonance
Average myocardial, endocardial, and epicardial curves for volunteers (a), patients with preserved (b), and reduced EF (c) over one cardiac cycle. The error bars represent the standard deviation across subject group. Time points were a significant difference (p < 0.05) between epicardial and endocardial torsion was observed are marked on the top with an asterisk (*)
