Sick Sinus Syndrome Associated with Head Trauma

Numerous central nervous system disorders can produce various electrocardiographic abnormalities due to vagal stimulation. These common abnormalities may include:QT prolongation, a large and inverted T wave and a prominent U wave etc. Sinus bradycardia and atrioventricular block have rarely been reported. We experienced a case of sick sinus syndrome, which was associated with a subarachnoid hemorrhage and subdural hematoma following a head trauma. (Korean Circulation J 2003;33 (12):1151-1154)
