Electromagnetic Compatibility Implantable Pacemaker Testing

The aim of the work was to assess the influence of electromagnetic non-ionizing radiation to cardiac pacemaker. The electromagnetic field can influence the pacemaker functionality and also the wireless communication between programmer and device. Electromagnetic compatibility is tested by direct induction of interference signal to the inputs of cardiac pacemaker according to technical specification. The tests were also made by generating of interference radio frequency signals to disturb the wireless telemetry communication. For testing purposes a circuit of artificial tissue has been designed and assembled, to which a cardiac pacemaker has been connected, as well as the antenna for short radio distance band. It has been proved that the cardiac pacemaker is resistant to co-phasally fed modulated electromagnetic field and also to the circuit of artificial tissue with the connected cardiac pacemaker. It has also been proved that the wireless telemetry communication is sensitive to the interference and disturbances. The non-proper cardiac pacemaker behavior change can endanger the patient's health during the diagnostics and therapeutics procedure. The results can help the physician in decision of patients with implantable pacemaker to dauntless medical procedure.
