| Summary: | The ambulatory monitoring of electrocardiographic signals, “Holter”, represents a decisive tool in the diagnostic
evaluation of patients with cardiac arrhythmias involved in pathological processes like cardiomyopathies, post-infarct stages,
injuries of the cardiac autonomous system, among others, as well as in the monitoring of implanted pacemakers. There are few
devices of this kind available in Colombia and most of them are very specialized and expensive for the majority of patients. We
built a cardiac monitoring and cardiac events registering system prototype that processes the ECG signals (amplification, filtration
and DC elevation), and stores the data acquired from the three main derivations DI, DII and DIII in an SD (Security Digital)
memory using the FAT (File Allocation Table) standard, which allows the reading of this information in any computer. Moreover,
we developed a software program that allows for the visualization of the registries previously stored in the SD memory for their
review and analysis. Using an ECG simulator, the frequencies 30 BPM, 120 BPM and 300 BPM and the amplitudes 0,5 mV, 1
mV and 2 mV were calibrated. It was found that the prototype errors were smaller than 1% for frequency and 6% for amplitude.
