BCG心冲击信号之Dataset:濒死病患数据集(patient deterioration impending death)

一、数据说明

  这是最近在Mendeley Data中发现的一个有关BCG信号的数据集,原地址链接在这:BCG - patient deterioration impending death
  数据集包含了16例患者从病情恶化到濒临死亡的BCG心冲击信号。通过由采样频率为330 Hz的2个(或4个)压电陶瓷传感器配备的感应垫获得的,其中传感器(i)位于心脏的下方,也是我们在数据展示部分作图画出的信号。
  Mendeley Data中对数据集的描述如下:
  The presented dataset consists of 16 ballistocardiographic records of patient deterioration impending death. It was obtained by ballistocardiographical sensory pads equipped by 2 (or 4) piezoceramic sensors with sampling frequency 330 Hz. When measuring, the pad is placed under the mattress of the patient’s bed. In the case of a 4-sensors pad, the sensors are placed: (i) approximately under the heart, (ii) under the right lunge on the same level as a sensor (i), (iii) under the left hip approximately on the level of the patient’s centroid, and (iv) on the same level under the right hip. On the other hand, in 2-sensors pads, only sensors (i) and (iii) are deployed. The lengths of records differ due to the different time intervals from onset of deterioration to death. The text file shows, when deterioration occurs by individual patients. The patients’ sex, age, height, weight and other descriptors are unknown.
