A study was undertaken to see if a group of patients could estimate their blood pressure (BP). One hundred and thirteen hypertensive patients were asked whether they could tell when their BP was high, and if so, how. Patients were also asked to give a categorical and a numerical estimate of their current BP. We found that patients did not appear to be able to predict their BP any more accurately than they could be expected to by chance. Patients who predicted correctly, and those who were incorrect, used the same symptoms to predict elevated BP. These were headache, a feeling of warmth, nervousness, dizziness, and pounding heart.
一项研究旨在观察一组患者是否能够估计自己的血压（BP）。研究询问了 113 名高血压患者是否能够判断自己的血压是否偏高，如果可以，他们是如何判断的。还要求患者对当前的血压进行分类和数值估计。我们发现，患者似乎无法比随机猜测更准确地预测自己的血压。预测正确的患者和预测错误的患者使用相同的症状来预测血压升高，这些症状包括头痛、感觉发热、紧张、头晕和心跳加速。
