Electrocardiographic changes associated with isolated right ventricular infarction.
Isolated infarction of the right ventricle is an extremely rare entity. A patient is described with diffuse interstitial lung disease who developed ST segment elevation in inferior and anterior leads on a routine electrocardiogram and at autopsy was found to have an isolated right ventricular infarct involving approximately 70% of the right ventricular circumference without involvement of the left ventricle and septum. This case illustrates that isolated right ventricular infarction in the presence of cor pulmonale and right ventricular hypertrophy can produce an injury current in the limb and precordial leads of the electrocardiogram which mimics that seen in typical transmural infarction of the left ventricle.
