Abstract:

BACKGROUND: The existing electrocardiogram (ECG) measurement strongly depends on medical professionals and inefficient high-intensity, or relies on automatic identification method which is not accurately enough. Thus, this is difficult to meet high-speed testing, accurate results and ease application for common people.
OBJECTIVE: To develop a new method that was simple and efficient to apply and very easy to learn.
METHODS: Algorithms were programmed and test software was developed by delphi7.0. ECG was drawn on screen. The apex, the starting point and the ending point as well as the J-point of each ECG wave were clicked by mouse or stylus. Then the wave parameters and an initial diagnosis could be quickly obtained by test software.
RESULTS AND CONCLUSION: The parameters of ECG waveform such as wave height, wave time, PR interval, ST segment, QT segment, PP/RR time, cardiac electrical axis and so on could be accurately measured, and heart rate, heart rhythm and the deflection of cardiac electrical axis could be diagnosed correctly. The method was simple to learn and easy to imply, and it was also efficient, quick and accurate. Thus, it could greatly improve the efficiency of measurement and analysis for specialists, and could meet application requirements of general medicals and ordinary people.
