RR列表获取

最后更新：2023年08月31日

接口能力

本接口可提取心电数据中的RR列表，用以绘制RR间期散点图或计算HRV指标。

请求方法

HTTP方法： POST
请求URL：http://api.amsu-new.com/amsu-analysis/v2/hrv/rr-list/
数据提交方式：multipart/form-data

Header参数：

字段	类型	描述
Authorization	Bearer Token	构造方式为`Bearer+(空格)+(Access Token)`

Body参数：

字段	类型	必传	范围	描述
ecg_file	File	是	*.ecg	二进制心电文件，以`.ecg`作后缀名，尺寸限制 100M 以内（约55小时离线数据）。数据将按照小端序 2字节`short`型被解析，可使用心电图查看工具观察您的文件是否能正确解析。
model	String	是	online、offline	心电记录模式，通过蓝牙采集的心电数据为`online`，在AMSU设备中存储的心电数据为`offline`
device	String	是	V6、S1	心电设备类型，对应蓝牙协议中「Device Information」-「Model Number」里包含的开发代号，心电衣（带）主机对应代号为`V6`，心电贴对应代号为`S1`

提示

若 model 为 online ，请在构造心电文件时用您自定义的信息（或任意值）填充前256个字节作为头部，若不构造头部，则文件中前1~2秒的心电数据不会参与分析。

返回参数

字段	类型	描述
rr_list	Array of Integer	RR间隙列表，RR间隙单位：ms

正确返回示例：

HTTP状态码：200

{
    "rr_list":[700,700,660,633,633,686,680,686,713,733,706,706,686,720,726,746,733,746,740,740,700,700,726,746,733,720,720,720,726,686,686,693,733,726,713,706,746,733,740,733,720,720,706,686,713,746,766,726,706,720,720,706,680,733,720,706,706,706,720,686,680,693,720,700,700,726,740,693,700,706,713,700,693,700,720,686,680,686,700]
}

错误返回示例：

HTTP状态码不为200

{
    "error": {
        "code": "COMMON.INVALID_FILE_TYPE",
        "msg": "Unsupported file type for field 'ecg_file'."
    }
}

错误码

HTTP状态码	错误码	说明
422	ECG.INVALID_DATA	无法从心电数据中有效识别出R波，此错误的可能原因有：1. 心电文件格式出错；2.心电数据未正常采集；3.心电数据质量过差

另请参见公共错误码
