| Abstract | ||
| Background:Velocity time integral (VTI) of the blood flow wave is derived from the analysis of the image of the Doppler wave. VTI can be utilized to determine hemodynamic information in certain cardiac disorders. Objective:To establish visual basic form for analysis of Doppler wave to determine velocity time integral (VTI) in normal subjects. Method:Doppler waves in twenty normal subjects were analyzed to determine VTI utilizing suitable computer program and visual basic form. Results:The parameters obtained from the analysis of Doppler wave (Ejection time (ET) and Mean blood velocity across aortic valve (Vm)) were utilized to determine VTI of the normal subjects studied as Mean, ±SD, ±SDE. Conclusion:The (VTI) was determined in normal subjects from their Doppler waves using a computer program of visual basic form that can be useful in diagnosing and following certain cardiac disorders. | ||
