title: [Cardiological aspect of Kearns' syndrome. Apropos of 3 cases, with histopathological study of the conduction tissue in one of them].
abstract: Three cases of Kearns syndrome are reported. The neuro-ophthalmological signs were comparable with ophthalmoplegia, pigmentary retinal degeneration and polymorphic neuro-muscular and sensory deficits. The electrocardiological signs were observed 2-4 years after the onset of the condition; the cause of death in each case was related to complete heart block. The post-mortem findings in one of the cases were spongial degeneration of the central nervous system and a seemingly primitive degeneration of the Bundle of His and its branches.
