美国BodyMedia公司推出无线远程心电图监测设备

一种新型无线监测器能够在长时间内通过从上肢获得的心电图连续监测心脏电生理活动。这种监测器还能够从机体其它部位获得心电图数据，而无需导线、贴附装置、或者其它设备。该技术由美国BodyMedia公司研制成功，整合了该公司的SenseWear袖带（一种在减肥和瘦身市场销售的可佩带身体监测器）。该公司指出这种监测器特别引人注目的地方是因为它挑战了心脏电生理学的传统认识：即心电图只能使用两个在空间上保持相当距离的电极来测量，而且最少要有两个电极必须靠近心脏。

研究人员报道说：与holter动态心电图监测相比较，该监测器在实验室检测与日常生活检测时都表现良好。该项研究是在斯坦福大学医学中心心脏电生理和心率失常科完成的。

“这个设备可以收集心脏节律、新陈代谢和机体整体信息，适合佩带数月或者数年。这或许能够有助于在临床诊断、治疗和处理领域开创一些令人兴奋的新方法，”该研究的主管Amin Al-Ahmad医生评论说。

Wireless Long-Term ECG Monitoring
 
A new wireless monitor can track the electrical activity of the heart continuously and for extended periods of time via an electrocardiogram (ECG) from the upper arm.

The monitor can also record ECG data from other locations on the human body without wires, adhesives, or other equipment. The technology was developed by BodyMedia, Inc. (Pittsburgh, PA, USA), which has integrated it into the company’s SenseWear armband, a wearable body monitor also sold to the weight-loss and fitness markets. The company points out that the monitor is especially noteworthy because it challenges conventional wisdom in electrocardiology that ECG can only be observed by using two electrodes spaced at considerable distance from each other, and that at least two electrodes must be closer to the heart than to each other.

The monitor performed well in both lab tests and free-living tests when compared to a holter monitor, reported researchers. The study was performed at Stanford University Medical Center Cardiac Electrophysiology and Arrhythmia Service (Palo Alto, CA, USA).

“These gathered heart rhythms, with the addition of the metabolic and contextual information this same device already collects, in a form that could deliver wearing compliance over months or even years, may open up several exciting new methods of clinical diagnosis, treatment, and management,”commented Dr. Amin Al-Ahmad, the study leader.
