Cardiac rhythm is controlled by membrane properties of the sinoatrial node and the activity of the neurohormonal and autonomic nervous system (ANS) modulation (Valensi et al.,2002; Vinik et al., 2003). There are two extrinsic ANS influences that determine the natural rhythm of the human heart, known as the sympathetic and parasympathetic signals.Generally, sympathetic activity decreases the interbeat (RR) intervals and decreases heart rate variability (HRV), whereas parasympathetic activity increases the RR intervals and increases HRV.
