摘要
心电信号发生器在心电信号相关教学培训和心电医疗设备检测中有着广泛的应用。现有的心电信号发生器通常通过存储于设备内的实测心电信号或者用数学函数波形拟合发生心电信号波形,在逼真度和灵活度上各有缺陷。本研究试图研究一种能综合现有心电信号模拟方法优点的新的模拟方法,使心电信号发生器生成质量更高,更丰富的信号,拓展它的应用范围。通过将单周期心电信号模板库与RR间期模拟信号结合,本研究实现了种类丰富,逼真度高,可自由调节心率特性的心电信号的模拟。这种方法同时还具有运算量小和节省存储空间的特点。
ECG generator has been widely used in medical education and training, equipment evaluation and research. Two kinds of signal are used in existing ECG generator, one is the stored real ECG signal, and the other is the simulated signal composed of mathematic function curves. We tried to explore a new way of ECG simulation which could generate a variety of EGG signal flexibly. Through the method of combining a single beat ECG template database and a RR interval simulator, a variety of ECG signal with freely pre-set features could be simulated. In addition to the flexibility and fidelity in generating simulated ECG signal, the whole process could be done on a platform with limited calculating resource and memory.
