A Comparison of Morphological Features Between Normal and Abnormal Left Ventricle in One Cardiac Cycle

Echocardiographic images are widely used in the diagnostic procedure of the cardiac function. Left ventricle plays a vital role in pumping the oxygenated blood to the complete body and maintain systematic circulation. In this study, the echocardiogram data of a normal and abnormal subject were collected. The frames were extracted from the video for one cardiac cycle. The left ventricle from each frame was segmented using image processing techniques. The parameters such as area, perimeter, and the centroid of the left ventricle were determined. These parameters were used to estimate the movement of the LV and measure the contraction and expansion of the chamber while pumping the blood out in one cardiac cycle. The comparison of these parameters in normal and abnormal LV show that the cardiac motion varies significantly. ECG signal was used as the biomarker for this estimation.
