自主平衡的概念将自主状态沿着从交感神经（S）到副交感神经（P）主导的双极连续体进行观察，而调节能力模型强调整体自主灵活性作为调节能力的标志。这两个概念进行了评估，他们的效用在表征模式的自主控制。测量P（高频心率变异性，HF）和S（射血前期，PEP）心脏控制。心脏自主平衡（CAB）的测量值是标准化P指数减去S指数的差值，心脏自主调节（CAR）的测量值是标准化P指数加上S指数。结果表明，CAR，而不是CAB，是一个重要的预测因素，以前发生心肌梗死，净人口统计学和其他变量，而CAB，而不是CAR，是一个重要的预测并发糖尿病。
The concept of autonomic balance views autonomic states along a bipolar continuum from sympathetic (S) to parasympathetic (P) dominance, whereas regulatory capacity models emphasize overall autonomic flexibility as a marker of the capacity for regulation. These two concepts were evaluated for their utility in characterizing patterns of autonomic control. Measures of P (high frequency heart rate variability, HF) and S (preejection period, PEP) cardiac control were obtained. A measure of cardiac autonomic balance (CAB) was derived as the difference in the normalized P index minus the S index, and a measure of cardiac autonomic regulation (CAR) was derived as the normalized P index plus the S index. Results reveal that CAR, but not CAB, was a significant predictor of the prior occurrence of a myocardial infarction, net of demographic and other variables, whereas CAB, but not CAR, was a significant predictor of concurrent diabetes.
