Résumé
The ejection fraction of the trabeculated cardiac ventricle of reptiles has not previously been measured. Here, we used the gold standard clinical methodology - electrocardiogram-gated flow magnetic resonance imaging (MRI) - to validate stroke volume measurements and end diastolic ventricular blood volume. This produced an estimate of ejection fraction in our study species, the red footed tortoise
