Este artigo apresenta o projeto de um Analisador de Desfibriladores-Cardioversores que afere múltiplos parâmetros: energia liberada, amplitude máxima e duração do pulso, tempo de subida da onda, atraso de sincronismo (em cardioversão) e a forma de onda da descarga desfibrilatória.

Effective maintenance of medical devices, such as defibrillators and cardioverters, requires preventive maintenance and repair, which should be carried out in many instances near the hospital unit where the devices are being used. It was developed an analog-digital analyzer, which fulfills the requirements of a calibrating equipment. The analyzer is powered by ordinary batteries, portable, and special care was taken to avoid shock hazards (optically isolated output to oscilloscope). The analyzer measures the following parameters: energy, peak voltage, pulse width and rise time. An internal resistance of 50 simulates the transthoracic impedance of human body. When a defibrillator pulse is discharged, the analyzer displays the selected parameter on a 3-digit LCD. To test cardioverters, the analyzer simulates the QRS complex and measures the response time,Four LED indicators display the cardioverter performance.
