Patients with Duchenne’s Muscular Dystrophy are at a high risk for both arrhythmias and heart failure and should be followed (and treated) agressively.
The heart failure occurs as a “dilated cardiomyopathy”, causing “systolic dysfunction”:

Treatment often includes angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs)plus Alpha-receptor blockade is clear for cardiomyopathy patients without muscular dystrophy, and there is no reason to avoid this standard regimen in muscular dystrophy patients:
Likewise, arrhythmias if present should be evaluated with monitoring and other testing such as a Holter monitor and possibly another EP study:
Lots of information for you, but I hope this helps,
