17 medicine undergraduates sitting their final examinations underwent continous ECG recording during a period of 3 h. Their usual heart rate was 71 +/- 9 per minute, accelerating to 149 +/- 13, most often at the moment of entering the examination room. This reaction was usual in all candidates despite their knowledge that the failure rate at the exams is always very low; all of this group likewise passed. Two subjects exhibited marked alterations in the terminal phase compatible with myocardial ischemia. In 6 cases severe sinus rhythm variations evidenced an unstable balance of the vagal and adrenergic stimulations. No other arrhythmias, augmentation in the number of premature beats or atrio-ventricular blockade were observed. Analysis of the results shows that the heart response to psychic aggression differs from that to physical effort.
17名正在参加期末考试的医学本科生在3小时内接受了连续心电图记录。他们的正常心率为每分钟71±9次，加速至149±13次，最常出现在进入考场的那一刻。尽管所有考生都知道考试不及格率一直很低，但这种反应在所有考生中都很常见；该组所有考生同样都通过了考试。两名受试者在末期出现了与心肌缺血相符的明显变化。在6例中，严重的窦性心律变化证明迷走神经和肾上腺素能刺激的平衡不稳定。未观察到其他心律失常、早搏数量增加或房室传导阻滞。结果分析表明，心脏对精神攻击的反应不同于对体力消耗的反应。
