Sr and Sc segmental curves obtained by 2DST analysis in a Saanen goat at rest, just after a standardized exercise test on treadmill, and 24 h after experimental induction of an ischemic cardiomyopathy. a Synchronous segmental Sr and Sc curves at rest in a healthy Saanen goat. b Synchronous segmental Sr and Sc curves in a healthy Saanen goat just after exercise. c Segmental Sr and Sc curves in a Saanen goat at 24 h after occlusion of the terminal branch of the circumflex coronary artery: posterior, inferior, and septal segments showed a severe left ventricular dyskinetic movement (white arrows) characterized by timing differences for Sr systolic peak and a systolic peak inversion for Sc. 2DST: two-dimensional speckle tracking; Sc: circumferential strain; Sr: radial strain
