Five patients with myocardial infarction were presented a completely representative television programme of 60 hours in order to examine the cardiac strain caused by consumption of television. During a period of 31 days they saw 108 selected TV-broadcasts. Heart activities were registered by long-time-ECG tapes and subjective data on wellbeing were recorded. The results show a total of 197 ES in 300 hours (149 VES and 48 SVES), six times VES by pairs and three times VES in bursts was seen. In one case an ST-decrease was found. There was no systematic correlation between ECG-changes, subjective disorders, and subjective preference of items on one hand and type, day-time and duration of the features on the other hand. The results of the study are regarded within the framework of a psycho-physiological stress paradigm. They may be generalized in such a way that watching television to a normal extent does not differ in its cardiac disturbances or cardiac strain from many other psychological activities in everyday postmyocardial-infarction life.
为了研究观看电视所引起的心脏负担，对五名心肌梗死患者播放了时长60小时、具有完全代表性的电视节目。在31天的时间里，他们观看了108个精选的电视节目。通过长时间的心电图磁带记录心脏活动，并记录有关健康状况的主观数据。结果显示，在300小时内共出现197次额外收缩（149次室性额外收缩和48次室上性额外收缩），成对出现室性额外收缩6次，成串出现室性额外收缩3次。在一例中发现ST段压低。一方面，心电图变化、主观不适以及对节目的主观偏好，与另一方面节目的类型、播出时间和时长之间没有系统的相关性。该研究结果是在心理生理应激范式的框架内进行考量的。可以这样归纳：在心肌梗死后的日常生活中，正常程度地观看电视在心脏干扰或心脏负担方面与许多其他心理活动并无差异。
