Clinical data of a 39-year-old patient with corrected transposition the great arteries, combined complete atrioventricular block and conduction along an accessory pathway, are presented. The features changes in structure system, rhythm characteristic this rare congenital heart disease discussed.
BACKGROUND Isolated cardiac conduction block is a relatively common condition in young and elderly populations. Genetic predisposing factors have long been suspected because of numerous familial case reports. Deciphering genetic predisposing factors of conduction blocks may give a hint at stratifying conduction block carriers in a more efficient way. METHODS AND RESULTS One Lebanese family an...
OBJECTIVE Atrial septal defect (ASD) is the second most common congenital heart defect (CHD) and is observed in families as an autosomal dominant trait as well as in nonfamilial CHD. Mutations in the NKX2-5 gene, located on chromosome 5, are associated with ASD, often combined with conduction disturbances, cardiomyopathies, complex CHD, and sudden cardiac death as well. Here, we show that NKX2-...
Genetic factors in the formation of the long R-R interval in ventricular arrhythmia associated with atrial fibrillation were investigated in the isolated rabbit heart which was perfused using Langendorffs technique. The transmembrane action potentials recorded from a single cell within the A-V node or within its vicinity were analyzed, and contiguous bipolar-lead electrograms simultaneously rec...
Air is usually the final method for thermal distribution in a building. The air distribution system (duct-work) may be located at several places inside or outside the building. The location of the ducts leads to thermal losses. These losses consist of: leakage, conduction, and thermal cycling. Traditionally, quantifying these loses requires temperature and flow data from many places in the syst...
To determine the frequency of atrioventricular conduction disturbances in aortic valve disease, 26 consecutive patients (age 54 +/- 2 years) with symptomatic aortic valve disease were studied by His bundle electrocardiography at the time of cardiac catheterisation and were compared with a group of patients who underwent cardiac catheterisation and were found to have coronary artery or mitral va...
Three macaque monkeys and 13 healthy human volunteers underwent diffusion tensor MRI with a 3 Tesla scanner for diffusion tract tracing (DTT) reconstruction of callosal bundles from different areas. In six macaque monkeys and three human subjects, the length of fiber tracts was obtained from histological data and combined with information on the distribution of axon diameter, so as to estimate ...
