Heart rate variability (HRV) is considered to be a means of assessing autonomic function. However, HRV alone provides mixed measures of autonomic function1–11 and, as a result, cannot provide much insight into the autonomic involvement in arrhythmia.1,6,10 When HRV analysis is employed in conjunction with respiratory activity (RA) analysis, it has been shown to independently, simultaneously, and… View more

Why Do We Need Risk Stratification Tools? Sudden death accounts for between 300,000 and 500,000 deaths each year in North America.1 Patients with a history of myocardial infarction (MI) have a four-fold higher risk of sudden death than those without such a history. Most sudden deaths in ambulatory populations result from life-threatening ventricular arrhythmias that lead to a cardiac arrest.2… View more

Arterial baroreceptors play a crucial role in the adjustment of the cardiovascular system to several surrounding conditions. In a simplified paradigm, baroreceptor stimulation results in arterial pressure changes that can modulate both sympathetic and vagal activity and, as a consequence, heart rate and myocardial electrophysiological properties, contractility and vascular resistance. Arterial… View more
