From: A case of a complete atrioventricular canal defect in a ferret
a Left laterolateral projection shows generalized cardiomegaly (vertebral heart score = 8) namely both ventricles and the left atrium (black arrows) with dorsal displacement of the trachea. There is also venous congestion (black asterisks) and bronchial lung pattern presence on the caudal lung lobes (white asterisks). b The dorsoventral view also demonstrates marked biventricular and left atrial enlargement. c Sinus rhythm (regular RR intervals) at a rate of 200–210 bpm. 100 mm / s and 1 cm = 10 mV. d Digital simultaneous superimposition of limb leads enhancing the measurement of diferent waves and intervals. There is a prolongation of the P wave suggesting left atrial (0.04 s; normal 0.01–0.03 s) and left ventricular enlargement (0.055 s; normal 0.02–0.05 s) [19]
