通用异常分析
最后更新:2023年08月31日
接口能力
本接口可识别心电数据中的多种疑似心律异常,包括房性早搏、室性早搏、心动过速、心动过缓、停搏、漏搏、插入性室早、室性心动过速、二联律、三联律等,统计其发生次数和时间节点,可同时适用于动态或静态场景下所采集的数据。
警告
本接口分析结果仅供参考,请勿用于医疗诊断用途!
请求方法
HTTP方法: POST
请求URL:http://api.amsu-new.com/amsu-analysis/v2/arrhythmia/common/results/
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 |
---|---|---|---|---|
height | Integer | 是 | 90 - 240 | 身高,单位:cm |
weight | Float | 是 | 30.0 - 200.9 | 体重,单位:kg |
age | Integer | 是 | 18 - 120 | 年龄 |
gender | Integer | 是 | 0 - 1 | 性别,男1 女0 |
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。
