There is no scientific literature that examines radiofrequency (RF) interference from Smart Meters with cardiac implantable electronic devices (CIEDs). The objective of this in vitro study was to assess any potential interference with Medtronic CIEDs (Medtronic Inc., Minneapolis, MN, USA).
In the Quebec testing, five models of Medtronic CIEDs were placed in an acrylic cylinder filled with a saline solution and faced a Landis+Gyr Smart Meter or Router (Landis+Gyr AG, Zug, Switzerland). The distance between CIEDs and the meter casing or router antenna was 10 cm. The Meter's normal operating conditions were modified to artificially set the number of impulsions at an abnormally high level (one, two, and three impulses per second). Each scenario was repeated one to five times, for 1 minute each. In the U.S. testing, 6 cm and 15 cm (∼2.25' and ∼6') separated the six models of Medtronic CIEDs from the Schlumberger Smart Meter (Itron Inc., Liberty Lake, WA, USA), which generally sent out a 96-bit Standard Consumption Message over 3 seconds. The transmission varied in frequencies along with the interval between cycles.
A total of 6,966 RF transmissions were completed during the 34 tests conducted in Quebec. In the United States, the CIED was exposed to the meter for 10 minutes to provide a minimum of 200 completed RF transmissions. No interference was observed in worst-case scenarios (testing of meters and CIEDs at their performance limits).
Landis+Gyr Smart Meters/Routers and Schlumberger Smart Meters do not interfere with the functioning of the Medtronic CIEDs tested, when placed, respectively, 10 cm and 6 cm and 15 cm apart.
尚无科学文献研究智能电表产生的射频(RF)干扰对心脏植入式电子设备(CIED)的影响。这项体外研究的目的是评估对美敦力CIED(美敦力公司,明尼阿波利斯,明尼苏达州,美国)的任何潜在干扰。
在魁北克的测试中,将五种型号的美敦力CIED放置在一个装满盐溶液的丙烯酸圆柱体内,并面对一台兰吉尔智能电表或路由器(兰吉尔股份公司,楚格,瑞士)。CIED与电表外壳或路由器天线之间的距离为10厘米。改变电表的正常运行条件,人为地将脉冲数设置为异常高的水平(每秒1次、2次和3次脉冲)。每个场景重复1至5次,每次1分钟。在美国的测试中,六种型号的美敦力CIED与斯伦贝谢智能电表(伊tron公司,自由湖,华盛顿州,美国)分别相距6厘米和15厘米(约2.25英寸和6英寸),该电表通常在3秒内发送一条96位的标准用电信息。传输频率随周期间隔而变化。
在魁北克进行的34次测试中共完成了6966次RF传输。在美国,CIED暴露于电表10分钟,以提供至少200次完整的RF传输。在最坏情况下(电表和CIED在其性能极限下进行测试)未观察到干扰。
当分别相距10厘米、6厘米和15厘米放置时,兰吉尔智能电表/路由器和斯伦贝谢智能电表不会干扰所测试的美敦力CIED的功能。
