Longitudinal regional strain obtained with speckle tracking echocardiography and mouse electrocardiography. A Longitudinal and B short axis views of the left ventricle (LV) highlighting the six-region segmentation used for speckle tracking analysis. C Longitudinal regional strain of the LV during a single cardiac cycle with each coloured line representing the systolic and diastolic strain of the region with the same colour code as in A. D Radial regional strain of the LV during a single cardiac cycle with each coloured line representing the systolic and diastolic strain of the region with the same colour code as in B. E Lead II from a surface electrocardiogram (ECG) obtained from a mouse using a six-lead device. F Magnification of the ECG trace included in de dotted square in E, highlighting normal ECG waves in mice. LV, left ventricle; bpm, beats per minute
