Cardiac Autonomic Functions are Altered in Patients with Acute Leukemia, Assessed by Heart Rate Variability

Cardiac Autonomic Imbalance in Children with Allergic Rhinitis

“…HRV parameters were found to be altered in various disorders, such as diabetic neuropathy (Bernardi et al 1992), heart failure (Saul et al 1988), preeclampsia (Yokusoglu et al 2009), acute leukemias (Nevruz et al 2007), depletion anemias (Yokusoglu et al 2007a), fetal type Minamata disease (Oka et al 2002), in preschool children with short nocturnal sleep (Sampei et al 2006), primary nocturnal enuresis (Dundaroz et al 2001;Unalacak et al 2004), cardiac resynchronization therapy (Akyol et al 2006) and during adrenocorticotropic hormone replacement treatment in infants with West syndrome (Hattori et al 2007).…”

The Altered Autonomic Nervous System Activity in Iron Deficiency Anemia

“…Indeed, decrease in HRV was suggested to predict coronary heart disease morbidity and mortality in patients after an acute coronary event (Odemuyiwa et al 1991). Moreover, HRV parameters were found to be altered in various disorders such as diabetic neuropathy (Kitney et al 1982), heart failure (Saul et al 1988), acute leukemias (Nevruz et al 2007), allergic rhinitis , fetal type Minamata disease (Oka et al 2002), in preschool children with short nocturnal sleep (Sampei et al 2006), primary nocturnal enuresis (Dundaroz et al 2001;Unalacak et al 2004), following a cardiac transplantation (Sands et al 1989) or cardiac resynchronization therapy (Akyol et al 2006) and during adrenocorticotropic hormone replacement treatment in infants with West syndrome (Hattori et al 2007). Veglio et al (1998) reported decreased sympathetic activity in patients with thalassemia major.…”

Increase in the Heart Rate Variability with Deep Breathing in Diabetic Patients after 12-Month Exercise Training

“…Heart rate variability (HRV) refers to the magnitude of the fluctuation in the number of heart beats per minute in conjunction with respiration (Nevruz et al 2007). HRV has recently become a popular non-invasive research tool in cardiology; in population studies, decreased HRV has been of predictive value for mortality among healthy adults (Pomeranz et al 1985;Tsuji et al 1994;Kristal-Boneh et al 1995;.…”
