Electrocardiography (ECG) of wild-type and Eya3-/- mutant mice. a) Electrocardiogram of a wild-type control. b) Electrocardiogram of an Eya3-/-animal is shown. Eya3 mutant mice of both sexes displayed several alterations compared to the control animals: the PQ-interval and the JT-interval are extended in mutants, while the amplitude of the QRS-complex is reduced in Eya3-/- animals (alterations are indicated by black arrows).
