An Holter ECG has been recorded for 24 h in 10 couples that had during such time a normal sexual contact. The age varied from 20 to 37 years for women, and 25 to 49 years for men. The average of maximum, medium and minimum rate was major in women than in men. During the initial phase of sexual activity an increase of about 30 beats per minute is verified up to an average rate of 104 b.p.m. without any differences between the two sexes. During realization phase the rate increased ulteriorly. This kind of increase is major and more prolonged in women (137 X 2.8 min.) with respect to men (126 X 2.1 min). The maximum rate observed during sexual contact wasn't superior to the maximum rate observed during the day. We conclude that a normal sexual activity doesn't represent a very pronounced strain, provoking a tachycardia equal to 60-70% of maximum rate of patient and for a short period of time. This should be kept in mind when judging on sexual activity of cardiac patients.
对10对在此期间有正常性接触的夫妇进行了24小时动态心电图记录。女性年龄在20至37岁之间，男性年龄在25至49岁之间。女性的最大、平均和最小心率平均值高于男性。在性活动初始阶段，心率每分钟增加约30次，平均心率达到104次/分钟，两性之间无差异。在性活动进行阶段，心率进一步增加。这种增加在女性中（137×2.8分钟）比男性中（126×2.1分钟）更显著且持续时间更长。性接触期间观察到的最大心率不高于白天观察到的最大心率。我们得出结论，正常的性活动并不代表非常明显的应激，只会引发相当于患者最大心率60 - 70%的心动过速，且持续时间较短。在判断心脏病患者的性活动时应牢记这一点。
