对48名无心脏病史的英国广播公司（BBC）交响乐团成员（43名演奏者和5名管理/技术团队成员）进行24小时动态ST段监测。这一时期包括理查德·施特劳斯和莫扎特在皇家节日大厅（n = 36）和拉赫玛尼诺夫和柴可夫斯基在巴比肯艺术中心（n = 21）的最后排练和现场表演（听众和广播）。在监测期间，1人（2%）出现短暂性ST段改变。现场表演时的平均心率明显高于排练时。拉赫玛尼诺夫和柴可夫斯基现场演奏时的平均心率显著高于施特劳斯和莫扎特现场演奏时的平均心率（n = 6）。管理和技术团队的平均心率高于球员。公认的心率昼夜节律模式，在早上醒着的时候达到峰值，在两个音乐会期间也发生了类似的变化，音乐家和管理/技术人员的主要峰值出现在晚上，早上的峰值较小。这项研究表明，环境因素在确定心率的昼夜模式中起着至关重要的作用。这在确定心血管压力的高峰期和为心绞痛患者量身定制药物治疗时具有重要意义。
Twenty four hour ambulatory ST segment monitoring was performed on 48 members (43 players and five members of the management/technical team) of the British Broadcasting Corporation (BBC) symphony orchestra without a history of cardiac disease. This period included final rehearsals and live performances (for audience and radio) of music by Richard Strauss and Mozart at the Royal Festival Hall (n = 36) and Rachmaninov and Tchaikovsky at the Barbican Arts Centre (n = 21). During the period of monitoring one person (2%) had transient ST segment changes. Mean heart rates were significantly higher during the live performances than during the rehearsals. Mean heart rates during the live performance of Rachmaninov and Tchaikovsky were significantly higher than during Strauss and Mozart in those (n = 6) who were monitored on both occasions. Mean heart rates in the management and technical team were higher than those of the players. The recognised circadian pattern of heart rate, with a peak in the morning waking hours, was altered similarly during both concert days, with a primary peak occurring in the evening hours and a lesser peak in the morning for both musicians and management/technical staff. This study showed that environmental factors are of primary importance in defining the circadian pattern of heart rate. This has important implications when identifying peak periods of cardiovascular stress and tailoring drug treatment for patients with angina pectoris.
