Electromagnetic interference by cellular phones with ophthalmic equipment

Electromagnetic interference with electrocardiogram recording of exercise test equipment.

Herein, we report a case of pseudosinus tachycardia resulting from an electromagnetic interference between a mobile phone and treadmill device. Electromagnetic interference from a charging mobile phone connected to the same socket with the exercise device turned the recording of a patient to that of pseudosinus tachycardia at approximately twice the rate of actual basal heart rate. Removal of t...

Interference by new-generation mobile phones on critical care medical equipment

INTRODUCTION The aim of the study was to assess and classify incidents of electromagnetic interference (EMI) by second-generation and third-generation mobile phones on critical care medical equipment. METHODS EMI was assessed with two General Packet Radio Service (GPRS) signals (900 MHz, 2 W, two different time-slot occupations) and one Universal Mobile Telecommunications System (UMTS) signal...

Electromagnetic interference of GSM mobile phones with the implantable deep brain stimulator, ITREL-III

BACKGROUND The purpose was to investigate mobile phone interference with implantable deep brain stimulators by means of 10 different 900 Mega Hertz (MHz) and 10 different 1800 MHz GSM (Global System for Mobile Communications) mobile phones. METHODS All tests were performed in vitro using a phantom especially developed for testing with deep brain stimulators. The phantom was filled with liquid...
