心电图和体积描记信号的测量是两种标准测量技术，其作为医院、家庭护理或其他卫生保健设施中的人体健康状况的非侵入性抽查方法来执行。因此，存在专门的电子系统，其执行两种测量中的任一种。对于一次单独分析一个信号，这是一种足够的方法，但是如果特别关注两个信号的相关性，则最好将测量系统联合收割机组合成一个系统，因为避免了不同测量之间的信号延迟。本文的目的是描述一个专门的硬件前端，这是能够高速，高精度，并发和时间同步记录的心电图和体积描记信号。它可以使两个信号相互关联，并生成新的数据，如脉搏传导时间。该参数被认为是血压或压力的标志，因此具有很高的研究兴趣。
The measurements of electrocardiographic and plethysmographic signals are two of the standard measurement techniques which are performed as noninvasive spot check methods of human health condition in hospitals, home-care or other health care facilities. Therefore, specialised electronic systems exist, which perform either of the two measurements. For the separate analysis of one signal at a time this is a sufficient approach, but if the correlation of the two signals is of particular interest it might be better to combine the measurement systems into one system as a signal delay between the different measurements is avoided. This paper aims to describe a specialised hardware frontend, which is capable of high speed, high precision, concurrent and time synchronised recording of the electrocardiographic and plethysmographic signals. It makes it possible to correlate both signals and to generate new data such as the pulse transit time. This parameter is presumed to be a marker of blood pressure or stress and is therefore of high interest of being investigated.
