Integration of the heart rhythmogenesis levels: heart rhythm generator in the brain.
We propose that along with the intracardiac pacemaker, a generator of cardiac rhythm exists in the central nervous system--in the efferent structures of the cardiovascular center of the medullar oblongata. Signals in the medulla oblongata arise as a result of the hierarchic interaction of the brain structures. Neural signals originating there in the form of bursts of impulses conduct to the hea...
متن کاملThe controllability of cardiac rhythm in elderly
Introduction: Recent reports have shown that rare fluctuations in cardiac cycles are ‘forgotten’ quickly in healthy individuals and it is possible to quantify the “memory length” of a physiological time-series using an inverse statistical approach. Methods: In the present study, we assessed the effect of aging on memory length in cardiac rhythm. Results: There was a long...
متن کاملCARDIAC ELECTRICAL DYSFUNCTION IN ACUTE BRAIN LESIONS
This study briefly reviews the heart abnormalities in diverse intracranial pathologies, including strokes, spontaneous and traumatic subarachnoid hemorrhage and intracranial hemorrhage, and presents the results of a one-year prospective study of heart abnormalities in patients with moderate to severe head injuries and subarachnoid hemorrhage. Different abnormalities such as: QT -interval, T...
متن کاملHierarchy of the heart rhythmogenesis levels is a factor in increasing the reliability of cardiac activity.
Along with the existence of an intracardiac pacemaker a generator of cardiac rhythm exists in the central nervous system - in the efferent structures of the cardiovascular center of the medullar oblongata. Neural signals originating there in the form of bursts of impulses conduct to the heart along the vagus nerves and after interaction with cardiac pacemaker structures cause generation of the ...
متن کاملThe development of cardiac rhythm.
T he cardiovascular system is the first organ system to form and function in the developing embryo. In the early stages the heart is a slow conducting, single tubular structure generating an even peristaltic contraction. During embryogenesis it then develops into a four chambered heart with synchronous contraction for a dual circulation. These synchronous contractions of the atrial and ventricu...
