Normal sinus rhythm/EKG Among the diagnostic procedures done to determine a cardiomyopathy are: * Physical exam * Family history * Blood test * ECG * Echocardiogram * Stress test * Genetic testing Classification Structural categories of cardiomyopathy Stained microscopic section of heart muscle in hypertrophic cardiomyopathy Cardiomyopathies can be classified using different criteria: * Primary/intrinsic cardiomyopathies * Congenital * Hypertrophic cardiomyopathy (HCM) * Arrhythmogenic right ventricular cardiomyopathy (ARVC) * Left ventricular noncompaction * Ion Channelopathies like the Long QT syndrome and the very rare Short QT syndrome * Catecholaminergic polymorphic ventricular tachycardia * Mixed * Dilated cardiomyopathy (DCM) * Restrictive cardiomyopathy (RCM) * Brugada syndrome * Acquired * Stress cardiomyopathy * Myocarditis, inflammation of and injury to heart tissue due in part to its infiltration by lymphocytes and monocytes * Eosinophilic myocarditis, inflammation of and injury to heart tissue due in part to its infiltration by eosinophils * Ischemic cardiomyopathy (not formally included in the classification, due to ischemic cardiomyopathy being a direct result of another cardiac problem) * Secondary/extrinsic cardiomyopathies * Metabolic/storage * Fabry's disease * Hemochromatosis * Endomyocardial * Endomyocardial fibrosis * Hypereosinophilic syndrome * Endocrine * Diabetes mellitus * Hyperthyroidism * Acromegaly * Cardiofacial * Noonan syndrome * Neuromuscular * Muscular dystrophy *<unk> 's<unk>  * Other * Obesity-associated cardiomyopathy
