Abstract		A well-known relationship between emotions and sudden cardiac death has been confirmed by clinical and experimental data in the last decades. Cerebrovascular disorders could be used, due to known localisation, as an example of brain lesion causing cardiac arrhythmias. Lesion of cerebral hemisphere in the region of insula and lesions in the brain stem can cause serious arrhythmias, including fatal ventricular fibrillation. There is an increasing evidence these arrhytmias occur due to the alterations of activity of sympathetic and parasympathetic autonomic nervous system function. Alteration of the activity of the autonomic nervous system has been studied using the spectrum analysis of the heart rate variability and measuring of plasma levels of the catecholamines. Cardiovascular instability following stroke relates the disinhibition of the insular cortex, especially of the right hemisphere. There is also a transient dysfunction of the autonomic nervous system in patients with the acute medullary stroke.
