BCG - patient deterioration impending death

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.

本数据集包含16份记录患者病情恶化直至死亡过程的心冲击描记（ballistocardiographic）数据。该数据集由搭载2个（或4个）压电陶瓷传感器、采样频率为330Hz的心冲击描记传感垫采集所得。采集时，该传感垫需放置于患者病床的床垫下方。针对4传感器构型的传感垫，传感器的布置位置如下：(i) 大致位于患者心脏下方；(ii) 与传感器(i)处于同一水平面的患者右肺下方；(iii) 大致处于患者质心水平面的左侧髋部下方；(iv) 与传感器(iii)处于同一水平面的右侧髋部下方。而对于2传感器构型的传感垫，则仅部署传感器(i)和(iii)。各条记录的时长存在差异，原因在于不同患者从病情恶化发作至死亡的时间间隔各不相同。配套的文本文件记录了每位患者病情恶化发作的时间节点。患者的性别、年龄、身高、体重及其他相关描述性信息均未公开。

背景概述

该数据集包含16条患者病情恶化至死亡前的ballistocardiographic记录，通过配备2或4个压电陶瓷传感器的感应垫采集，采样频率为330Hz。记录长度因患者病情恶化到死亡的时间不同而异，但缺少患者的基本描述信息。
