In military recruits, sudden cardiac death rates have been reported as varying from 2 to 13 per 100,000 per year which are mostly related to exercise. However, the development of structural heart changes that may be associated with ventricular arrhythmias have not been reported among this cohort, despite them undergoing endurance training similar to athletes. Here, we report two cases where military personnel were found to have life-threatening cardiac arrhythmias associated with structural heart disease, highlighting the importance of early recognition and treatment of these arrhythmias.

Muscular dystrophy (MD) connotes a heterogeneous group of inherited disordersaffecting skeletal and cardiac muscle. Inseveral forms of MD, the cardiac disease may be the predominant manifestationof the underlying genetic myopathy. The cardiacinvolvement is due to progressive interstitial fibrosis and fatty replacement inboth the atria and ventricles, which may lead to cardiomyopathy, conductiondefects and tachyarrhythmias.

Hypertension, once rare, is rapidly becoming a major public health burden in sub-Saharan Africa (SSA). However, data on its prevalence, awareness, treatment and control are paltry, especially for rural communities.
