电子健康纪录，又称为电子健康档案，简称EHR，是电子化的个人健康纪录（病历、心电图、医疗影像等），电子健康纪录可以经由电脑或网络访问，可以包含现今与过去个人的健康信息。除此之外，电子健康纪录也能够包括医学相关的参照数据、医疗处置、药物使用、人口统计数据、其他与非医疗的管理数据等等……。然而，一个理想的电子健康纪录系统，现今还没有一个软件或是供应商所能够建置出来。

An electronic health record (EHR), or electronic medical record (EMR), refers to the systematized collection of patient and population electronically-stored health information in a digital format. These records can be shared across different health care settings. Records are shared through network-connected, enterprise-wide information systems or other information networks and exchanges. EHRs may include a range of data, including demographics, medical history, medication and allergies, immunization status, laboratory test results, radiology images, vital signs, personal statistics like age and weight, and billing information.
