Radiography will show left ventricular hypertrophy (seen in Dobermans & Boxers), left atrial enlargement (seen in Dobermans & Boxers), generalised cardiomegaly (seen in giant breeds), [[Heart Failure, Left-Sided|left sided congestive heart failure]] signs e.g. pulmonary congestion & edema and [[Heart Failure, Right-Sided|right sided congestive heart failure]] signs e.g. pleural effusion and ascites.

Electrocardiography (ECG) will show rhythm disturbances e.g. [[Atrila Fibrillation|atrial fibrillation]] (giant breeds), ventricular arrhythmias (Doberman Pinchers, Boxers), conduction disturbances and characteristic signs of hypertrophy.

Echocardiography will show a hypokinetic left ventricle (i.e. reduced fractional shortening therefore reduced contractility), reduced ejection fraction (i.e. % end diastolic volume ejected at systole), decreased ventricular wall thickness, left atrial enlargement and mitral regurgitation.
