Research on Calibration Method and Uncertainty Evaluation of Pacemaker Analyzers

External pacemakers, also known as temporary pacemakers, have been widely used in clinical settings, significantly reducing patient mortality rates. Pacemaker analyzers are utilized to measure the parameters of pacemakers, ensuring their accuracy, as these parameters are critical to patient safety. Regular calibration is essential since pacemaker analyzers have been widely used. However, measurement institutions and published measurement standards rarely focus on the calibration of pacemaker analyzers. This paper designs a calibration method that uses a digital multimeter and a waveform generator to calibrate parameters such as internal resistance, current amplitude, pulse width, rate, and energy of the pacemaker analyzer. A program by C# in Visual Studio is developed to control the calibration instruments, therefore improving measurement efficiency. At the end of the paper, uncertainty evaluation of the calibration results is conducted.
