Development of an alternative method for the calibration of ECG simulators
ETALONS, S.A. de C.V., 64640 Monterrey, Mexico
In Mexico, the concern on improving the healthcare system has always been of great importance. The relevance of this development is the impact on the improvement of the quality of health system along with human health condition. An ECG simulator oversees calibrating ECG machines, including monitoring, and diagnose. Thus, it is important to be completely sure if an ECG simulator is working according to their specifications, in order to assure the good performance of electrocardiographs. The aim of this method is to describe a calibration procedure for ECG simulators.
A home-designed amplifier was built to amplify the small signal from the ECG simulator for the oscilloscope to display to be able to measure its amplitude and frequency, and compare it with manufacturer’s specifications. The amplifier was calibrated using Fluke ProSim 8, as a result a calibration curve and equation was obtained. The restlessness arises from experience and investigations from other authors where they have reported misdiagnosis in certain diseases due to misreading of ECGs, noticing that medical staff base their diagnosis on medical devices. For that reason, an erroneous diagnosis can lead to wrong treatments for patients representing a waste of medical resources and more important potential death.
