5 Causes Of T-Wave Abnormality. T wave is basically the diagrammatically representation of ventricular polarization called electrocardiography. The structure of a T wave is like slight inverted upward stroke that follow a peak generated by R and S waves. One heart beat is represented in form of Q, R, S and T wave. The abnormality in T waves may be indicated by longer, flatter or higher peaks in the diagram. The measurement of heart beat in such a way makes it possible to diagnose heart related problems easily.
