[Anti-digoxin antibodies in severe digitalis poisoning in an 11-day old infant. Review of the literature].

Acute digitalis intoxication bringing into play the prognosis for survival is a rare complication in children, particularly in the neonatal period. We describe the case of an accidental massive digitalis intoxication in a newborn aged 11 days, which caused a complete atrioventricular block and a state of cardiogenic shock. The outcome was favorable four hours after administration of the first dose of anti-digoxin antibodies, with a complete reversal of clinical and electrocardiographic signs.

[Comparison of gas exchange and hemodynamic variables during 2 types of exercise tests. Cycle-ergometry and the ergometric table].

The development of stress echocardiography on an ergometric table has increased the number of stress tests in the decubitus position, whereas most of the information currently available concerns stress tests in the sitting position or on the treadmill. In order to study the influence of this position of stress testing, the authors compared the results obtained in a series of 15 patients without cardiac disease (Group I) and another series of 15 coronary patients (Group II) undergoing the two types of stress testing, in the vertical position on a bicycle ergometer and in the lateral decubitus position on the ergometric table. Effort tolerance on the bicycle ergometer was significantly greater in terms of work load (202 +/- 35 vs 180 +/- 36 watts (p < 0.

Tilt table testing of young adult patients: improved speed and sensitivity using an isoproterenol bolus and a continuous 60 degrees tilt.

The tilt table is a diagnostic device used to induce vagal syncope and determine etiology. Sensitivity enhancing techniques, such as the administration of isoproterenol, can be applied to children and young adults to compensate for the otherwise low sensitivity (20%-30%) observed in that population. This study describes an improved test that offers a simplified approach while decreasing the amount of time involved by up to 50%, without compromising sensitivity.
