Abstract

Background

Electromagnetic interference (EMI) between tablet computers (tablets) and cardiac implantable electronic devices (CIEDs) in the abdomen of adults remains unclear.

Methods

We aimed to determine the magnetic flux density (MFD) of tablets, measure the distance at which EMI was triggered, and assess the susceptibility of abdominally implanted CIEDs to EMI.

Results

We studied 17 tablets and 2 CIED models. The measured MFD of tablets was 638 Gauss. EMI occurred at a 3.2 cm distance. A simulated patient using a tablet experienced EMI episodes for 357.2 s in 10 min.

Conclusions

Tablets may generate sufficient MFD to induce EMI in abdominally implanted CIEDs.

片剂诱发电磁干扰对腹部心脏装置的影响：一项基于模拟患者的研究

成人腹部平板电脑与心脏植入式电子设备之间的电磁干扰（EMI）尚不清楚。方法测定片剂的磁通密度（MFD），测量诱发电磁干扰的距离，评价腹腔植入cied对电磁干扰的易感性。结果共研究17片和2个CIED模型。测得片剂的MFD为638高斯。电磁干扰发生在3.2 cm的距离。一个使用片剂的模拟患者在10分钟内经历了357.2秒的EMI发作。结论片剂可产生足够的MFD，诱发腹腔植入cied的EMI。
