Supraventricular Tachycardia in Patients with Right Hemisphere Strokes
Stroke 23:362-366, Lane,R.D.,et al, 1992
See this aricle in Pubmed
Article Abstract
All four patients with supraventricular tachycardia had right hemisphere strokes(p=0.05).There was a nonsignificant trend for left hemisphere stroke patients to have more severe ventricular arrhythmias.These data provide partial support for the hypothesis that the two cerebral hemispheres have a differential influence on the nature and severity of arrhythmias following an acute stroke.We speculate that parasympathetic tone was diminished ipislateral to the affected hemisphere associated with a reciprocal rise in sympathetic tone on that side and recommend that a prospective study be undertaken to test this hypothesis more definitively.
