[Electrocardiographic evaluation of myocardial co-involvement in Duchenne muscular dystrophy: prognostic implications in a case with multiple localizations].

After a review of the literature on myocardial involvement (MI) in Duchenne's progressive muscular dystrophy (DMD), the authors report a case with an extensive MI. This severe myocardial functional impairment is a poor index in the prognosis of DMD. The authors emphasize the use of echocardiography in the screening of MI in DMD.
