In recent years, electrocardiogram technology has become increasingly widely available, embedded into dedicated portable devices, smartwatches and, now, even bathroom scales.

近年来，心电图技术已变得越来越广泛，嵌入专用便携式设备，智能手表以及现在甚至浴室秤中。

The latter advancement comes courtesy of Withings, whose Body Scan smart scale is equipped with a six-lead ECG—among several other health-analyzing features—and is newly cleared by the FDA, according to a recent announcement (PDF) from the company.

根据该公司最近的一份公告（PDF），后者的进步来自Withings，其Body Scan smart scale配备了六导联心电图以及其他几种健康分析功能，并由FDA新批准。

“With Body Scan, we will turn the morning weigh-in into a sophisticated home health check with access to holistic health data and personal health programs created by medical professionals,” Eric Carreel, founder and president of Withings, said in the announcement. “We will empower our users with the ability to take meaningful actions based on medical-grade data, adding a new dimension to ongoing lifestyle and chronic condition management through the ultimate in-home health experience.”.

Withings的创始人兼总裁Eric Carreel在公告中说：“通过身体扫描，我们将早上进入复杂的家庭健康检查，获得由医疗专业人员创建的整体健康数据和个人健康计划。“我们将赋予用户根据医疗等级数据采取有意义行动的能力，通过最终的家庭健康体验为持续的生活方式和慢性病管理增加新的维度。”。

The device, dubbed a “connected health station” by Withings, will begin its U.S. rollout at the end of September. It’ll retail for just under $400 and come with a three-month subscription to the app-based Withings+ health improvement program.

该设备被Withings称为“连接健康站”，将于9月底开始在美国推出。它的零售额不到400美元，并且有三个月的订阅基于应用的Withings+健康改善计划。

The smart scale collects ECG readouts via three sets of electrodes: two located on either side of the device’s retractable handle and one embedded in the base of the scale. Body Scan is equipped with an algorithm that analyzes the heart readings to flag possible signs of atrial fibrillation, with the results displayed both on the scale’s own three-inch LCD screen and in the accompanying Withings app..

智能秤通过三组电极收集心电图读数：两组位于设备可伸缩手柄的两侧，另一组嵌入刻度的底部。身体扫描配备了一种算法，可分析心脏读数以标记可能的房颤迹象，结果显示在秤自己的三英寸LCD屏幕和随附的Withings应用程序中。。

Meanwhile, those data and other health information will be used to calculate a user’s “vascular age,” which compares how their heart health and overall wellness compare to the standards for their age group.

同时，这些数据和其他健康信息将用于计算用户的“血管年龄”，该年龄将比较他们的心脏健康状况和整体健康状况与年龄组标准的比较。

Beyond the heart, Body Scan can also assess a user’s small nerve activity, which has a hand in regulating some involuntary functions of the cardiovascular and digestive systems. During a 20-second reading, electrodes in the scale’s plate send out a small current to the feet, while sensors watch for a response from the sweat glands that may indicate degeneration among the small nerve fibers..

除了心脏之外，身体扫描还可以评估用户的小神经活动，其可以调节心血管和消化系统的一些非自愿功能。在20秒的读数期间，秤板中的电极向脚发出小电流，而传感器观察汗腺的响应，这可能表明小神经纤维之间的退化。。

That degeneration may be linked to conditions including peripheral nerve damage, diabetes and Parkinson’s disease, but nerve activity can be improved through diet, activity and other lifestyle changes—which the Withings app can lay out for users if needed.

这种退化可能与周围神经损伤，糖尿病和帕金森病等疾病有关，但神经活动可以通过饮食，活动和其他生活方式的改变来改善，如果需要，Withings应用程序可以为用户提供。

This electrodermal activity monitoring technology is a product of Withings’ early 2022 purchase of Impeto Medical, maker of the Sudoscan nerve-assessing sensors.

这种皮肤电活动监测技术是Withings于2022年初购买Impeto Medical，Sudoscan神经评估传感器制造商的产品。

On top of those high-tech features, Body Scan also provides the weight readings of a typical scale. Thanks to its built-in sensors and retractable handle, Withings says the readings are accurate to within 0.1 pounds or 50 grams.

除了这些高科技功能之外，身体扫描还提供典型秤的重量读数。由于其内置的传感器和可伸缩手柄，Withings表示读数精确到0.1磅或50克以内。

But, of course, the device also takes those readouts to the next level: In addition to reporting the user’s body weight, it also analyzes their basal metabolic rate and overall “metabolic age,” while the electrodes in the handle and base can be used to paint a picture of their body composition. In that three-second analysis, the system can determine what percentage of the user’s body mass is water, fat, muscle or bone, while also breaking down that composition for the torso, arms and legs alone..

但是，当然，该设备还将这些读数提高到一个新的水平：除了报告用户的体重外，它还分析他们的基础代谢率和整体“代谢年龄”，而手柄和底座上的电极可以是用于描绘其身体成分的图片。在该三秒分析中，系统可以确定用户体重的百分比是水，脂肪，肌肉或骨骼，同时还可以单独分解躯干，手臂和腿部的成分。。
