Change in heart rate variability in relation to a significant ST-event associates with newborn metabolic acidosis.

  Background & Objective : Heart failure is a clinical syndrome and increases in rate by aging. Because changes in ECG and electrolytes are variable, specific and sometimes independent to the disease with different methods to be diagnosed, in this study we tried to find a way to diagnose them.   Materials & Methods: This is a retrospective descriptive-analytic study. Data was collected from dec...

The Effects of Maternal Opium Abuse on Fetal Heart Rate using Non-Stress Test

Background: Opium is one of the most commonly abused opiates in developing countries including Iran. Considering the importance of maternal health on the newborn, we aimed to assess the effect of opium abuse on fetal heart rate (FHR) characteristics in a sample of pregnant women in Zahedan, Southeast Iran.Methods: This cross-sectional study was done on 100 pregnant women referring to Ali-Ibn-Ab...

Heart-Brain Coherence; Heart-Rate Variability (HRV); Reading Anxiety; TestEdge Program

Based on psychophysiological research, coherent heart-brain interaction can change afferent cardiac signal pattern sent to the brain. Accordingly, the present study aimed at facilitating the emotion-cognition interaction through HeartMath Institute self-regulated emotional techniques to investigate the efficacy of heart-brain coherence on reading anxiety reduction that significantly enhances at...

Comparison of the effect of aerobic exercise in water with two different temperatures with outside water environment on the index of very low frequency waves of heart rate variability in active young men

Introduction and purpose: Cardiac response to body core temperature variation measured with the very low-frequency parameter of heart rate variability. The aim of this study was to investigate the variability of very low frequency due to different temperatures of aerobic training in water and dry. Materials and methods: 40 academic active male were selected as research subjects. Then, all subje...
