Many parameters of normal cardiovascular function suggest that variability is an intrinsic property of a healthy cardiovascular system and gives it the necessary flexibility to adapt to various stressors. In the congestive heart failure syndrome, this variability is significantly decreased, reducing the ability to adapt to stressors and increasing the risk for adverse events. Reduced variability is a useful unifying concept in understanding the many interactive aspects of the congestive heart failure syndrome. J Clin Basic Cardiol 2000; 111-3.
