Temporal and spectral analysis of ventricular fibrillation in humans.

Purposes: Analysing ventricular fibrillation (VF) rate and regularity at different sites and at different times may help understanding some of the mechanisms underlying VF in humans.

Methods: Twelve episodes of VF (19.4 ± 5.

Live 3D echocardiography with the pediatric matrix probe.

Three-dimensional echocardiography (3DE) enables new views of heart valves and the septa to be imaged. While the previous 3DE system was cumbersome, the recent introduction of live 3DE allowed for routine use of the technique in adult patients. Here, we report our initial experiences in adapting live 3DE and the adult matrix probe to the pediatric population.

[Transposition of the great arteries with pulmonary valvular stenosis and intact interventricular septum. Discussion of management strategies with respect to one case].

The authors report the case of a neonate with transposition of the great arteries (TGA) with pulmonary stenosis (PS) and intact Interventricular septum. The child was born at full term without a prenatal diagnosis with cyanosis developing at the 12th hour. After emergency atrioseptostomy, detransposition was performed on the 6th day.

[Evaluation of left ventricular diastolic function in children by doppler tissue imaging].

Left ventricular diastolic function may change at an early stage in cardiac disease. It is often difficult to assess in daily practice. The use of Doppler tissue imaging at the annulus has been validated in adults.
