Cardiac conduction disorders in children.
Conduction disorders result in cardiac arrhythmias that may be fatal. Histiocytoid cardiomyopathy, Arrhythmogenic right ventricular dysplasia, Isolated noncompaction of the left ventricle, Long QT syndrome (LQTS) and Brugada syndrome, are all well described. Congenital short QT syndrome is a new familial primary electrical disease of the heart, which is characterized by abnormally short QT inte...
متن کاملConduction System in Cardiac Rejection
Correlation of electrocardiographic abnormalities occurring postoperatively with lesions of the conduction system found at autopsy was done in 20 dogs which had received cardiac homografts. The incidence of arrhythmias closely paralleled the severity of rejection injury found within the heart and specifically within the conduction system. Severe pathological changes in the conduction system (gr...
متن کاملLineages of the Cardiac Conduction System
The cardiac conduction system (CCS) initiates and coordinately propagates the electrical impulse to orchestrate the heartbeat. It consists of a set of interconnected components with shared properties. A better understanding of the origin and specification of CCS lineages has allowed us to better comprehend the etiology of CCS disease and has provided leads for development of therapies. A variet...
متن کاملPacing the Human Cardiac Conduction System
Specialized fiber electrograms were recorded from selected sites along the His bundle and bundle branches during open-heart surgery in 26 patients. The heart was then paced from the same recording sites. Stimuli applied to the proximal His bundle recording site always resulted in His bundle pacing, which was characterized by a stimulus artifact-to-QRS interval which equaled or very nearly equal...
متن کاملDevelopment of the cardiac conduction system
The heterogeneous tissues of the cardiac pacemaking and conduction system are responsible for setting, maintaining and coordinating the rhythmic pumping of the heart (reviewed Thompson et al., 1995; Moorman et al., 1998; Gourdie et al., 1999). Anomalous development of this specialized network has been implicated in pediatric arrhythmia and other congenital abnormalities of cardiac activation (S...
