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.

摘要

背景

成人腹部平板电脑与心脏植入式电子设备（CIED）之间的电磁干扰（EMI）仍不明确。

方法

我们旨在确定平板电脑的磁通密度（MFD），测量触发EMI的距离，并评估腹部植入的CIED对EMI的敏感性。

结果

我们研究了17款平板电脑和2种CIED模型。测得的平板电脑MFD为638高斯。EMI在3.2厘米的距离处发生。一名使用平板电脑的模拟患者在10分钟内经历了357.2秒的EMI发作。

结论

平板电脑可能会产生足够的MFD，在腹部植入的CIED中诱发EMI。
