[Electrocardiographic anomalies in relation with infarction in the territory of the anterior choroid artery].

Electrocardiographic changes are seen in 5-17% of acute ischemic stroke, but there is scarpe clinical evidence to correlate stroke location with cardiac abnormalities. A 17-year old man had infarct in the territory of the anterior choroidal artery with major but reversible electrocardiographic changes. Infarction involved the substantia innominata containing the ventral amygdalofugal pathway. Electrocardiographic changes could result from a small hemispheric lesion of structures involved in autonomic control. Correlation studies of stroke location with electrophysiologic changes should help to determine patients at risk for cardiac arrhythmia and prevent sudden death.
