Detailed heart rate variability analysis in athletes.

Objective: Heart rate variability (HRV) analysis has been used to evaluate patients with various cardiovascular diseases. While the vast majority of HRV studies have focused on pathological states, our study focuses on the less explored area of HRV analysis across different training intensity and sports. We aimed to measure HRV in healthy elite and masters athletes and compare to healthy, but non-athletic controls.

Breech presentation: its predictors and consequences. An analysis of the Hungarian Tauffer Obstetric Database (1996-2011).

Introduction: Breech presentation is linked to abnormal pregnancy outcomes. However, the causality of this association is unknown. We aimed to investigate predictors of term breech presentation and pregnancy outcomes of breech presentation.

Prevalence of physiological and pathological electrocardiographic findings in Hungarian athletes.

Unlabelled: In Hungary, ECG is a keystone of routine athletic screening. Its significance is based on simplicity, quickness and high informative value as well as the fact that appearance of pathological ECG signs can precede the formation of structural heart diseases. During screening of healthy athletes, we studied the incidence of athletic ECG changes and pathological ECG abnormalities.

Self-rated health is associated with the length of stay at the intensive care unit and hospital following cardiac surgery.

Background: Recently, a considerable amount of evidence suggested that anxiety, depression and other psychosocial variables might influence the outcomes of cardiac surgery. This study investigated the relationship between length of stay at the intensive care unit (ICU) and hospital after surgery and different psychosocial variables (e.g.
