Journal ArticleDOI
Respiratory sinus arrhythmia: why does the heartbeat synchronize with respiratory rhythm?
Fumihiko Yasuma,Junichiro Hayano +1 more
TL;DR: RSA or heart rate variability in synchrony with respiration is a biological phenomenon, which may have a positive influence on gas exchange at the level of the lung via efficient ventilation/perfusion matching and evidence has accumulated of a possible dissociation between RSA and vagal control of that heart rate.
Journal ArticleDOI
Accuracy of assessment of cardiac vagal tone by heart rate variability in normal subjects.
Junichiro Hayano,Yusaku Sakakibara,Yusaku Sakakibara,Akira Yamada,Akira Yamada,Masami Yamada,Masami Yamada,Seiji Mukai,Seiji Mukai,Takao Fujinami,Takao Fujinami,Kiyoko Yokoyama,Kiyoko Yokoyama,Yosaku Watanabe,Yosaku Watanabe,Kazuyuki Takata,Kazuyuki Takata +16 more
TL;DR: The correlations of 11 indexes of heart rate variability were examined with pharmacologically determined cardiac vagal tone in 15 normal subjects at supine rest to indicate that most of the time and frequency domain analyses in use provides an accurate and common measure of cardiacvagal tone at rest.
Journal ArticleDOI
Decreased magnitude of heart rate spectral components in coronary artery disease. Its relation to angiographic severity.
Junichiro Hayano,Y. Sakakibara,Masami Yamada,Nobuyuki Ohte,Takao Fujinami,Kiyoko Yokoyama,Y. Watanabe,K. Takata +7 more
TL;DR: The results indicate that coronary artery disease is associated with vagal dominant impairment in autonomic cardiac function and that reduction in the vagal cardiac function correlates with the angiographic severity.
Journal ArticleDOI
Effects of Exercise and Stress Management Training on Markers of Cardiovascular Risk in Patients With Ischemic Heart Disease A Randomized Controlled Trial
James A. Blumenthal,Andrew Sherwood,Michael A. Babyak,Lana L. Watkins,Robert A. Waugh,Anastasia Georgiades,Simon L. Bacon,Junichiro Hayano,R. Edward Coleman,Alan L. Hinderliter +9 more
TL;DR: For patients with stable IHD, exercise and stress management training reduced emotional distress and improved markers of cardiovascular risk more than usual medical care alone.
Journal ArticleDOI
Short- and long-term effects of cigarette smoking on heart rate variability.
Junichiro Hayano,Masami Yamada,Masami Yamada,Yusaku Sakakibara,Yusaku Sakakibara,Takao Fujinami,Takao Fujinami,Kiyoko Yokoyama,Kiyoko Yokoyama,Yosaku Watanabe,Yosaku Watanabe,Kazuyuki Takata,Kazuyuki Takata +12 more
TL;DR: It is suggested that smoking causes an acute and transient decrease in vagal cardiac control, and that heavy smoking causes long-term reduction in vagAL cardiac control in young people and blunted postural responses in autonomic cardiac regulation.
