Echocardiographic and Electrocardiographic Findings in Pediatric Patients With Neurological Findings.

Neurological disorders in pediatric patients represent a significant cause of morbidity and mortality worldwide. These disorders may have multifactorial etiologies , including congenital , infectious , metabolic , inflammatory , and vascular causes , with clinical presentations ranging from seizures to motor deficits and altered consciousness.

The interplay between neurological conditions and cardiovascular involvement has gained increasing attention in recent years. Cardiac manifestations may occur secondary to neurological diseases due to autonomic dysregulation , systemic inflammation , or direct neuro cardiac interaction , potentially affecting patient outcomes.

Several studies have demonstrated that pediatric patients with neurological diseases, such as epilepsy, cerebral palsy, and acute encephalitis, may exhibit significant echocardiographic and electrocardiographic changes. These changes may be transient or persistent, and recognizing them early is crucial for comprehensive patient management.

Moreover, neurological complications may also arise as a consequence of primary cardiac disease. Conditions such as congenital heart disease, infective endocarditis, or shunt lesions can predispose to embolic stroke, brain abscess, or hypoxic-ischemic injury, representing critical intersections between heart and brain.

Electrocardiographic abnormalities are frequently observed in children with congenital and acquired heart disease, and some of these changes are associated with neurological complications. For instance, prolonged QT interval or QT dispersion has been linked to an increased risk of arrhythmia-related cerebral hypoperfusion and syncope, which in turn can precipitate transient ischemic attacks or seizures.
