Database_Validation Rmssd Selftraining UMH

Two different devices that recorded HRV were used for the measurements: a Biopac MP35 3-lead electrocardiogram (Biopac Systems, Goleta, CA, USA) and the new smartphone application (Selftraining UMH (Elche, Spain)). The electrocardiogram was connected to a computer via USB port and the mobile application was linked using Bluetooth to a previously validated HR sensor chest strap (Polar H10, Polar Electro Oy, Kempele, Finland). Four consecutive 6-minute recordings were captured by alternating the supine position with the seated position in a resting state. During the 6-minute period, the first minute was perfomed to stabilize the HRV signal and the last 5 minutes in each position were taken for the subsequent analysis.

本次测量采用两款不同的心率变异性（HRV, Heart Rate Variability）记录设备：一款为Biopac MP35型三导联心电图仪（Biopac Systems，美国加利福尼亚州戈莱塔市），另一款为新型智能手机应用程序Selftraining UMH（西班牙埃尔切市）。该心电图仪通过USB端口连接至计算机，而该移动应用则通过蓝牙与此前已验证的心率传感器胸带（Polar H10，芬兰肯佩勒市博莱电气公司（Polar Electro Oy））配对连接。实验通过交替采取静息状态下的仰卧位与坐位，共采集4段连续6分钟的记录。在每段6分钟的采集周期中，前1分钟用于稳定心率变异性信号，每个体位下的最后5分钟数据将被用于后续分析。
