Key result
A 12-year-old boy with hypertrophic cardiomyopathy presented with syncope attributed to intermittent complete atrioventricular block.
Case Report (n=1)
Highlights complete heart block as a potential cause of syncope in pediatric patients with hypertrophic cardiomyopathy.
May signal AV conduction risk in pediatric HCM with syncope; leaves open need for targeted screening studies.
Summary We report a 12-year-old boy with hypertrophic cardiomyopathy presenting with syncope. His electrocardiogram showed first-degree atrioventricular block, complete right bundle branch block, conduction delay in the anterior fascicle of the left bundle branch, and intermittent complete atrioventricular block. We detected hypertrophic cardiomyopathy in the mother. The relationship between the diseases is discussed, and interpreted in the light of previous descriptions.
