Transtorno do sistema de condução atrioventricular caracterizado por desvio do eixo para a esquerda para a idade (eixo do plano frontal entre -45 ° e -90 °), padrão qR na derivação aVL, tempo de pico R na derivação aVL de 45 ms ou mais e duração do QRS que não atende aos critérios dependentes da idade para bloqueio completo de ramo (menos de 120 ms em adultos, menos de 100 ms em crianças de 4 a 16 anos de idade e menos de 90 ms em crianças com menos de 4 anos de idade) | |||
