Whereas the diagnosis and treatment of certain heart diseases, including the ones that cause cardiac arrhythmia, depend on the usage of electromedical equipment such as electrocardiographs, cardiac monitors, holters, pacemakers and defibrillators / cardioverters, it is vital that such products be technically evaluated and certified as a way to check their performance, limitations, and ability to fulfill their functions, in order to ensure safety against electrical hazards and command errors, as well as to ensure that they are manufactured in accordance with the Technical Standards in force.The registration and certification of these products is compulsory in Brazil, and, in order to be marketed, they must comply with the requirements of the series ABNT NBR IEC 60601/ 80601of Technical Standards, which establish the essential safety and performance requirements that these products must meet. This paper describes testing methods, testing procedures, and the way cardiac equipment parameters have to be measured and evaluated providing all the measuring instruments and requirements for test performing and metrology. It also shows are the final results of tests indicating that some important parameters of the evaluated equipament are not in accordance with the standards adopted in Brazil.Finally, the findings and conclusions are presented, with incitements for future works, in order to contribute to pursuit of continuous improvement. This research intends to contribute as a benchmark for Testing Laboratories with similar interest in obtaining testing technical capacity, and is also an orientation to for companies that produce heart medical equipment in accordance with the requirements of the standards adopted in Brazil.
