Patients with neurogenic stunned myocardium most often have no history of heart disease. Despite this, they present with wall motion abnormalities, ejection fraction is less than 40%, and troponin levels of less than 2.8ng/ml [1]. Atrial Fibrillation commonly develops, ushering in a tachycardia which eventually increases the oxygen-demand in the myocardium, further worsening myocardial ischemia [3]. Common ECG findings include T wave inversion, U wave inversion, and QT prolongation [1].
Please answer the following questions: the incidence on NSM associated with seizure versus other causes as well as the incidence of cerebral T
waves.
As the insular cortex maintains autonomic control of the cardiovascular system [4], direct or indirect involvement of this area, whether by seizures, subarachnoid hemorrhage, or stroke, may precipitate cardiogenic shock secondary to neurogenic stunned myocardium.
