Chang J, Hwang S, Yi S, Kim Y, Lee Y, Kim Y, et al.
Psychiatry Clin Neurosci . 2014 Jul; 69(5):283-91. PMID: 25066617
Aims: Antipsychotic-induced autonomic dysregulation may lead to a wide range of subjective side-effects in schizophrenia patients. Using heart rate variability (HRV) measures, we prospectively examined the relationship between subjective side-effects...

Kim J, Yi S, Lee J, Kim Y
J Clin Psychopharmacol . 2013 Jan; 33(1):69-73. PMID: 23277266
Previous studies have suggested the utility of nonlinear complexity measures of heart rate variability (HRV) in evaluating the regulatory capacity of the neuroautonomic system. The purpose of the present study...

Yi S, Lee K, Shin D, Kim J, Kim H
Yonsei Med J . 2012 Dec; 54(1):55-61. PMID: 23225799
Purpose: Although obesity has been associated with imbalances in cardiac autonomic nervous system, it is unclear whether there are differential relationships between adiposity measures and heart rate variability (HRV) measures....

Yoo C, Lee K, Yi S, Kim J, Kim H
Korean J Fam Med . 2012 Jun; 32(6):334-40. PMID: 22745871
Background: The aim of this study was to investigate the relationship between heart rate variability (HRV), the Framingham risk score (FRS), and the 10-year risk of coronary heart disease (CHD)...

Chang J, Ha K, Yoon I, Yoo C, Yi S, Her J, et al.
Prog Neuropsychopharmacol Biol Psychiatry . 2012 Jun; 39(1):136-42. PMID: 22699029
Evidence from previous studies suggests autonomic dysregulation in patients with major depressive disorder (MDD). Antidepressant treatment may also affect central autonomic function. We investigated whether the type of antidepressant might...

Chang J, Yoo C, Yi S, Her J, Choi H, Ha T, et al.
Psychosom Med . 2012 Mar; 74(5):495-500. PMID: 22408133
Objective: Alterations in neuroelectrical activities coincide with major depressive disorder (MDD). This study examines the pattern of cerebral activity and cardiac autonomic parameters of euthymic women with recurrent MDD. Methods:...

Yoo C, Jung D, Ahn Y, Kim Y, Kim S, Yoon H, et al.
Psychiatry Res . 2011 Aug; 195(1-2):76-82. PMID: 21831451
Determining the exact duration of seizure activity is an important factor for predicting the efficacy of electroconvulsive therapy (ECT). In most cases, seizure duration is estimated manually by observing the...

Chang J, Yoo C, Yi S, Hong K, Lee Y, Oh H, et al.
Prog Neuropsychopharmacol Biol Psychiatry . 2010 Apr; 34(6):924-9. PMID: 20423720
Neurocardiac dysregulation has been reported in schizophrenia. Indices of heart rate variability (HRV) are useful in assessing the status of cardiac autonomic regulation. We explored within-subject changes in HRV indices...
9.
Kim J, Yi S, Ahn Y, Lee K, Yang S, Kim Y
Psychiatry Investig . 2010 Feb; 6(4):294-8. PMID: 20140128
Objective: The percentage of successive normal cardiac interbeat intervals greater than 50 msec (pNN50) is a widely used heart rate variability measure, which is useful in identifying the neuroautonomic dysfunction...

Chang J, Yoo C, Yi S, Hong K, Oh H, Hwang J, et al.
Prog Neuropsychopharmacol Biol Psychiatry . 2009 May; 33(6):991-5. PMID: 19427888
The cardiac autonomic dysfunction has been reported in patients with schizophrenia. Heart rate variability (HRV) provides non-invasive indices of cardiac autonomic modulation. This study examined whether patients with schizophrenia may...
