Effect of weight loss following bariatric surgery on myocardial dispersion of repolarization in morbidly obese patients.

Background: Weight-stable obese subjects have an increased risk of arrhythmias and sudden death, even in the absence of cardiac dysfunction, and the risk of sudden cardiac death (SCD) with increasing weight is seen in both genders. The mechanism of unexplained deaths in obese patients is still unclear and may be related to ventricular repolarization abnormalities. The aim of this study is to determine the effect of severe obesity on spatial and transmural ventricular repolarization and to clarify the influence of bariatric surgery with a consequent substantial weight loss on arrhythmogenic substrate in the morbidly obese population.

[Eco-color-Doppler venous catheterization of internal jugular vein in obese patient].

Aim Of The Study: The Authors analyzed the results of 120 central venous catheterisms of internal jugular vein performed by eco-color-Doppler from January 2000 to December 2004 in obese patients candidated to bariatric surgery.

Results: As the considerable adiposity and post-operation necessities, this procedure has been very useful. The average performing time was 10 minutes, 95.
