OBJECTIVE: Isolated ventricular noncompaction is a rare primary @entity74 characterized by persistent embryonic myocardial morphology without any other @entity299 . @entity943 are frequently present, including both @entity591 and conduction disturbance. Our study aimed to describe the electrocardiographic findings and to correlate them with the clinical presentation and cardiac magnetic resonance imaging findings. METHODS: We retrospectively reviewed 24 @entity1 diagnosed with isolated ventricular noncompaction (IVNC) by cardiac magnetic resonance imaging. Correlations were investigated between @entity943 and the site of ventricular noncompaction, number of noncompacted segments, presence of @entity82 , and @entity1002 . RESULTS: The mean age was 42.7  13.1 years. @entity1 were first presented with @entity712 in 41.7% and @entity943 in 45.8%. Electrocardiogram was abnormal in 91.6% of @entity1 ; the most common @entity154 was @entity714 ( @entity714 ) (41.7%), followed by @entity943 (29.1%), repolarization abnormalities (29.1%), and @entity1165 (20.8%). A normal left ventricular systolic function was frequently observed in @entity1 who first presented with rhythm disorders than @entity712 (p=0.008). There was also a delayed diagnosis of IVNC when presented with @entity943 versus @entity712 (p=0.02). We found no correlation between @entity943 and the noncompaction site or @entity82 , except for @entity714 , which was associated to left ventricle lateral wall involvement (p=0.028). No correlation between @entity299 and the number of noncompacted segments, @entity82 , or @entity943 was demonstrated. CONCLUSION: While electrocardiographic abnormalities are frequent in isolated ventricular noncompaction, no specific patterns were identified. More large studies are needed for stratification of arrhythmic risk of this highly arrhythmogenic substrate.
