[Ventricular arrythmia and sport practice: A Gallavardin's ventricular tachycardia during exercice in healthy heart, about a case and review of the literature]. / Arythmie ventriculaire et activité sportive : tachycardie ventriculaire d'effort de Gallavardin sur cœur sain, à propos d'un cas et revue de la littérature.

Regular physical exercice has undeniable cardiovascular benefits and improves life expectancy. This benefice seems limited to moderate intensity exercises. Intense and chronic physical exercice would lead to heart structural changes. For a long time, knowledge of these cardiac effects seemed limited to the left ventricle. Since more authors have shown that right ventricle is vulnerability to the effects of intense chronic training. We report a Gallavardin-type ventricular stress tachycardia in a young with healthy hearted; in whom a right infundibular arrhythmogenic focus has been found in the absence of structural alteration of the right ventricle. Intense athletic activity may reveal a latent arrhythmogenic focus through sympathetic activation. Ablation was the preferred therapeutic strategy, preferred to drug therapy and derived from an analysis of risk-benefit ratios.

[Effects on the newborn infant of thiopental and propofol used in anesthetic induction in cesarean section]. / Efectos sobre el neonato del tiopental o propofol utilizados en la inducción anestésica de la intervención cesárea.

OBJECTIVES: To compare the effects of an anesthetic induction dose of thiopental to that of propofol on the vitality of the neonate, as measured by Apgar score and the interval between extraction of the newborn and unassisted respiration. PATIENTS AND METHODS: One hundred ASA I-II women undergoing cesarean section were randomly assigned to two groups of 50. Anesthesia was induced with thiopental 4 mg/kg in one group; in the other group, propofol 2 mg/kg was used. Time intervals recorded were induction-to-extraction, uterine incision-to-extraction and extraction-to-unassisted respiration. An Apgar score was recorded 1, 5 and 10 min after birth. For statistical analysis, each group was divided into three subgroups, in accordance with the reason for performing the cesarean section: subgroup 1, elective cesarean; subgroup 2, emergency cesarean due to dystocia or failure; subgroup 3, emergency cesarean section due to acute fetal distress. RESULTS: Means of intervals for induction-extraction and uterine incision-extraction showed no significant differences. All induction-extraction intervals were under 10 min (4.94 +/- 1.55 min) and all uterine incision-extraction intervals were under 180 sec, with most staying under 90 sec (43.13 +/- 25.76 sec). No statistically significant differences were found for vitality between the two groups of neonates. CONCLUSIONS: If the induction-extraction interval is 10 min or less, both thiopental (4 mg/kg) and propofol (2 mg/kg) given in a single dose for induction of general anesthesia in all types of cesarean section are equally safe for the newborn infant.
