Charcot-Marie-Tooth disease and cardiac arrhythmias.

A child with several episodes of supraventricular tachycardia was treated in our department from birth to the age of seven years. At this age a diagnosis of Charcot-Marie Tooth disease was made on the basis of the results of clinical and neurophysiological examinations, blood analysis and a neuromuscular biopsy. The association between sensorimotor neuropathies and cardiac involvement is controversial, especially at pediatric ages. We describe a case presenting this association.
