Autonomic Aging: A dataset to quantify changes of cardiovascular autonomic function during healthy aging

Autonomic function regulating blood pressure and cardiac rhythm progressively declines with increasing age. Impaired cardiovascular control promotes a variety of age-related conditions such as dementia, or Alzheimer’s disease. This study aims to provide a database of high-resolution biological signals to describe the effect of healthy aging on cardiovascular regulation. Electrocardiogram and continuous non-invasive blood pressure signals were recorded simultaneously at rest in 1,121 healthy volunteers. 

自主调节血压和心脏节律的功能随着年龄的增长而逐渐衰退。心血管控制的损害促进了多种与年龄相关的疾病，如痴呆或阿尔茨海默病。本研究旨在提供一套高分辨率生物信号的数据库，以描述健康老龄化对心血管调节的影响。在休息状态下，对1,121名健康志愿者同时记录了心电图和连续的非侵入性血压信号。
