SensSmartTech database of cardiovascular signals synchronously recorded by an electrocardiograph, phonocardiograph, photoplethysmograph and accelerometer

The SensSmartTech database comprises cardiovascular signals synchronously recorded by electrocardiograph (ECG), phonocardiograph (PCG), photoplethysmograph (PPG) and accelerometer (ACC) at heart rates at rest and after activity (HRs). It is composed of 338 30-s recordings taken from 32 healthy volunteers. Recordings contain information from 10 channels: 4 ECG (limb, V3 and V4 leads), 1 PCG (measured at heart apex), 4 PPG (measured at carotid and brachial arteries at two light wavelengths each) and 1 ACC (measured between V3 and V4 ECG electrodes), along with the recording time of each signal. The original recordings are stored in CSV format. Resampled recordings are stored in WFDB format. The large HR range with the average minimum on the set of 83 ± 11 bpm and the average maximum on the set of 143 ± 14 bpm, along with several recordings per heart relaxation period, enable studying of the cardiovascular dynamics and gaining insights into the corresponding cardio-respiratory and electro-mechanical couplings. Of particular clinical significance are the opportunities to derive corrections of multiparameter biomarkers for HR.SensSmartTech数据库包含由心电图（electrocardiograph, ECG）、心音图（phonocardiograph, PCG）、光电容积描记图（photoplethysmograph, PPG）与加速度计（accelerometer, ACC）同步采集的心血管信号，采集场景覆盖静息状态与活动后的心率（HRs）场景。该数据集共包含32名健康志愿者的338段时长为30秒的记录。每段记录包含10个通道的信号信息：4路心电图信号（分别为肢体导联、V3导联与V4导联）、1路心音图信号（采集于心尖部位）、4路光电容积描记图信号（分别于颈动脉与肱动脉采集，每种动脉采用两种光照波长）、1路加速度计信号（采集于V3与V4心电图电极之间），同时附带各信号的记录时间。原始记录以CSV格式存储，经重采样后的记录则以WFDB格式存储。该数据集的心率跨度较大，集合内平均最低心率为83±11次/分钟，平均最高心率为143±14次/分钟，且每个心脏舒张周期均包含多段记录，这为心血管动力学研究以及深入解析相应的心肺耦合与电机械耦合机制提供了支撑。尤为具备临床应用价值的是，该数据集可用于推导针对心率的多参数生物标志物校正方案。
