Diagnosis
Neurogenic heart syndrome (NHS). The neurogenic myocardial injury is one of the possible complications after acute ischemic stroke. The patho-physiological mechanisms may be related to exaggerated stress-induced release of catecholamines with subsequent acute imbalance of autonomic control of the heart [1]. The autonomic imbalance may lead to hypercontraction of sarcomeres, cardiac stunning, coronary vasospasm, ECG and left ventricular wall motion abnormalities and life-threatening arrhythmias
