This finding may be because (a) the parasympathetic component of baroreceptor regulation of HR was impaired in patients with cardiac dysfunction [35] or (b) the overstimulation of sympathetic nerves was inconsistent with the inhibition of the vagal nerve in patients with left ventricle dysfunction, which leads to uncoordinated control of autonomic nervous system and sinoatrial node, resulting in a disorder of HR regulation.
Pacemaker cells located in the heart muscle contract in response to impulses originating in a location called the sinoatrial (sinus) node.
Ivabradine is a sinoatrial node modulator that provides additional heart rate reduction.
The electrical impulses are generated by a cluster of cells in the right atrium that form the sinoatrial node, or SA node.
The sinoatrial nodal artery is anatomically significant, because it is the landmark for the identification of the sinoatrial node (SA node), which is the natural pacemaker of heart.

The electrophysiology of the heart with the sinoatrial (SA) node and the atrioventricular (AV) node are the primary pacemaker cell groups in the heart and may be implicated in diseased conditioning of the heart through de-synchronization and body trauma.
HR in normal adults depends on the pacemaker activity of the sinoatrial node cells and constantly varies under the influence of a number on unmodifiable and modifiable factors.
Chronic stress exposures also lead to adaptive changes of neural and glial cells in the central nervous system (McEwen 2007), which controls the heart via innervation of the sinoatrial node.
The presence of multiple ostia in anterior aortic sinus, suggestive of emergence of the following arteries directly from the aorta: RCA, right conus artery, sinoatrial nodal artery, vasovasorum of pulmonary trunk and anamolous origin of LCA.
Among the methods available to assess the status of the autonomic nervous system, HRV has emerged as a simple and noninvasive method to assess the sympathovagal activity at sinoatrial level (TASK FORCE OF THE EUROPEAN SOCIETY OF CARDIOLOGY AND THE NORTH AMERICAN SOCIETY OF PACING AND ELECTROPHYSIOLOGY, 1996).
