Intracardiac Conduction Intervals: An Electrophysiological Mirror of the Brazilian Population
Este Editorial é referido pelo Artigo de Pesquisa "Analysis of Conduction Intervals in Normal Electrophysiological Studies: Establishment of Reference Values the Brazilian Population".
In the current edition of the International Journal of Cardiovascular Sciences, Leiria et al. have published a historical cohort of 124 electrophysiological studies considered normal, and evaluated three parameters of intracardiac conduction: (1) PA interval; (2) AH interval and (3) HV interval. The reference values for baseline electrophysiological parameters in the Brazilian population are of great interest due to their unique characteristics.
Since the description of the electrical potential in the end portion of the atrioventricular (AV) node by, Dandamudi and Vijayaraman related Wilhelm His Jr., in 1893, which would come to be named the bundle of His, cardiac electrophysiology has added knowledge to both the diagnosis and treatment of the different forms cardiac arrhythmias, and to the field of artificial cardiac stimulation.
