ABSTRACT

As taquicardias com complexos QRS alargados (QRS com duração igual ou superior a 120ms) constituem um desafio na prática clínica. O diagnóstico diferencial (DD) entre uma taquicardia ventricular (TV) e uma taquicardia supra-ventricular (TSV) com condução aberrante (complexos QRS alargados) é de suma importância para uma correta conduta terapêutica anti-arritmica. Um erro na diferenciação entre uma TV e uma TSV com aberrância pode acarretar a escolha inadequada do fármaco, aumentando, deste modo, o risco de consequências fatais. Os autores ressaltam as principais dificuldades em se estabelecer este DD através do eletrocardiograma convencional, bem como postulam a utilização do algoritmo de Brugada que apresenta alta sensibilidade e especificidade no auxílio diagnóstico das taquicardias com QRS largos. Em relação a terapêutica mais aceita para a reversão à ritmo sinusal utilizamos o algoritmo proposto pelo Advanced Cardiac Life Support (ACLS)

ABSTRACT

Genetic markers and total intelligence quotient (IQ) assessed by WISC (Wechsler Intelligence Scale for Children) were studied in children of both sexes from Santiago, Chile. Heterozygous boys for phosphoglucomutase 1 (PGM) and heterozygous girls for haptoglobin (Hp) had lower IQ than homozygoytes. For ABO system, B girls had lower and B boys had higher IQ than children with other ABO phenotypes. These differences were highly significant with the two tailed t'-test (Student's t-test with the Welch-Satterthwaite correction for degrees of freedom), and most of them remained significant after the correction for multiple comparisons. Girls had greater variance of IQ than boys. Relationships between homozygotes and heterozygotes were found in two independent studies. Thus, the genetic relationship found here seems likely to be a true biotic effect.
