In situations where an urgent decision-making is necessary, it is important to rely on input from more than one source. By using concept of virtual instrumentation, ECG signal can be digitized and transferred to computer for further processing. Software in computer enables use of modern tools for digital signal processing. One of such tools is time-frequency analysis with continuous wavelet transform. The same (digitized) signal can be presented to the cardiologist in standard - time domain, but also simultaneously in time-frequency domain. By looking at both presentations of the same signal and by interpreting them, making a diagnosis becomes more reliable. The process of software development, with the goal mentioned, requires continuous monitoring and correction of faults that might appear in interpreting of two different presentations. We have decided to use standard DMAIC model in the process of software development and maintenance in order to make and keep quality of proposed decision making tool in electrocardiography.
