最近的证据表明，在心理挑战期间表现出过度心血管反应的倾向与心血管疾病的风险之间可能存在关系。然而，可靠地评估这种反应的有效技术是最低限度可用的。匹兹堡大学、迈阿密大学和杜克大学目前正在开发一种用于评估心血管对实验挑战的反应性的测试电池。一台与IBM-AT兼容的微型计算机被用来同时收集生理数据和呈现实验室应激源。正在收集的数字化心血管数据包括EKG、心阻抗图(ICG)、心音图和外周脉搏波测量。血压读数也被收集并存储在磁盘上。这台电脑呈现了三款具有挑战性的视频游戏，每一款都旨在引发心血管反应。正在使用和开发用于数字化信号的标准化评分的处理程序。为了协助流行病学研究，已经组建了一个流动测试单位，以便在不同的地理位置方便地管理测试电池。正在开发的测试组件将增加对应激诱导的心血管反应的流行病学和临床评估的可行性，这可能证实反应性和心血管疾病之间的联系。
Recent evidence has suggested a possible relationship between the tendency to exhibit excessive cardiovascular reactions during psychological challenge and the risk of cardiovascular disease. Valid techniques for reliably assessing such reactions are, however, minimally available. A test battery for the assessment of cardiovascular reactivity to experimental challenge is currently being developed at the University of Pittsburgh in conjunction with the University of Miami and Duke University. An IBM-AT compatible microcomputer is being used for the concurrent collection of physiological data and presentation of the laboratory stressors. Digitized cardiovascular data being collected include EKG, Impedance Cardiogram (ICG), phonocardiogram, and a peripheral pulse wave measure. Blood pressure readings are also being collected and stored on disk. The computer presents three challenging video games, each designed to elicit cardiovascular reactions. Processing programs are being used and developed for the standardized scoring of the digitized signals. To assist in epidemiological research a mobile testing unit has been assembled for the easy administration of the test battery in varying geographical locations. The test battery being developed will increase the feasibility of epidemiological and clinical assessment of stress-induced cardiovascular responses which may substantiate a link between reactivity and cardiovascular disease.
