1:1 atrioventricular conduction in congenital complete heart block.
نویسندگان
چکیده
A female neonate with congenital complete heart block developed atrioventricular conduction through an accessory pathway. Despite sinus rhythm and an adequate heart rate she developed severe dilated cardiomyopathy and died at age 14 months. This case illustrates that underlying heart block can be present in individuals with asymptomatic Wolff-Parkinson-White syndrome and that the dilated cardiomyopathy that occasionally accompanies autoimmune congenital heart block is not primarily caused by bradycardia.

We report the case of a patient followed since childhood for congenital complete atrioventricular block. At 28 years of age, atrioventricular conduction through an accessory pathway with long conduction times was detected. Periods of atrioventricular conduction alternated with periods of atrioventricular block. Sinus tachycardia and 1:1 exclusive conduction through the accessory pathway develop...
متن کاملLesions of the Atrioventricular Conduction
DURING the repair of congenital defects of the venitricular septum, various disturbances of cardiac function may occur.1'Permanent complete heart block has been the most serious of these disturbances. Right bundle-branch block seems benign. Inereased knowledge of the anatomic features of the atrioventricular (AV) conduction system has resulted in surgical technics that have nearly eliminated co...

متن کاملSecond-degree Atrioventricular (Mobitz 1) Heart Block in a 52-hour-old Newborn: A Very Rare Case Report
Background: Cardiac conduction disorders are rare syndromes in neonates and children. According to the literature atrial septal defect, especially ostium secundum type, is associated with atrioventricular (AV) block. Wenckebach conduction heart block is very rare in a neonate; however, there is a dearth of research on the prevalence of this type of heart block regarding the neonates and pediatr...
متن کاملCongenital Familial Cardiac Conduction Defects.
THE familial occurrence of conduction system disturbances has been reported infrequently in medical literature. Morquio, in 1901,1 reported clinical signs of impaired atrioventricular conduction in five boys in a family of eight children. There was no evidence of consanguinity and the defect did not occur in immediate ancestors nor in collateral branches of the family. In 1903, Sir William Osle...
