The hereditary cardiomyopathic hamster of the UM-X7.1 strain is a particular experimental model of heart failure (HF) leading to early death in muscular dystrophy (dystrophin deficiency and sarcoglycan mutation) and heart disease (δ-sarcoglycan deficiency and dystrophin mutation) in human DMD.
Secondary aims were to assess associations between ECG abnormalities and evidence of cardiac disease by echocardiography, as well as to estimate the relationship between dystrophin mutation site and an abnormal ECG.
